Is Twitter Basically Broken?

Posted by Harry McCracken on October 21, 2009 at 3:36 pm

Yesterday evening here at the Web 2.0 Summit, Twitter CEO Ev Williams sat onstage and confidently declared “Scalability today isn’t an issue for Twitter.” If so, the Failwhale is a big fat liar: When he appears, he’s accompanied by a message that “Twitter is over capacity” and that there are “Too many tweets!” And while the Failwhale is no longer the constant companion of Twitter addicts that he was for awhile last year, he’s been rearing his head frequently this week. Ads the Twitter status page explains:

Um, sounds like scalability issues to me, even if they’re temporary!

I understand that 100 percent uptime is an impossible dream, that even the the folks who know more than anyone in the world about providing robust Web surfaces have their periodic issues, and even that there are far more important problems in the world than occasional Failwhale sightings. But I’m still trying to make sense of Ev Williams’ statement. I’m assuming he didn’t mean to suggest that Twitter thinks its current level of reliability is as good as it gets. I’d love to hear Ev Williams or others at the company talk about why Twitter still chokes as often as it does, and what it’s doing about it. (Maybe the status message’s references to changes it’s making for “the future growth of the product” are a good sign.)

This morning at the conference, Facebook VP of Engineering Mike Schroepfer spoke about how how Facebook–which surely ranks among the most reliable major Web services-keeps on keeping on. Facebook’s a far larger company than Twitter, with more resources, more engineers, and more servers. But its predictability still makes for a striking contrast with Twitter. I choose to be an optimist: If Facebook can run like a top, so can Twitter. And maybe it will someday.

For the moment, I lump Twitter in with my cell-phone service–it works most of the time, but I’m not the least bit startled when it doesn’t….

Yup, Bing Gets Twitter Search

Posted by Harry McCracken on October 21, 2009 at 12:16 pm

Back in July, Bing added some not-very-exciting Twitter integration to its search results. Today at the Web 2.0 Summit here in San Francisco, Microsoft confirmed the news that All Things Digital’s Kara Swisher broke (and my colleague Ed Oswald wrote about): Bing has a deal with Twitter to provide a much more sophisticated level of Twitter search within Bing. We just saw a demo of the new features, which are supposed to be live at http://www.bing.com/twitter shortly. (I’m getting that home page, but an error when I try to search.)

(As Kara reported, Bing also has a deal in place to provide results from Facebook, but those tools won’t show up immediately. Given the face that Facebook is so much more private than Twitter, I’m curious to see how Microsoft makes Facebook-within-Bing make sense.)

It’s impossible to judge a search engine from a brief onstage demo, but Microsoft’s goals are worthy, at least. Basically, it sounds like it’s trying to provide the service that Twitter’s own search should be but isn’t: The results weed out duplicate retweets and pointless blather, try to determine the most worthy Twitter users and push their items to the top, and show where short URLs are going. It’s also got features to spotlight Tweets that contain useful links. And the home page you get before you do a search provides Tweets on hot topics grouped by subject matter–a little like what Google News might look like if it pointed to nothing but Tweets.

The service will be especially useful if it’s easier to find old-but-still-useful Tweets than it is at Twitter itself, but it’s not clear how far back its index goes. (Qi Lu, Microsoft’s head online honcho, wasn’t sure.)

If Bing’s Twitter search turns out to be good, one obvious question about it is this: Shouldn’t really good Twitter search be available at Twitter? We don’t know much about Twitter’s plans for its own search, but it’ll be a tad odd if the best way to find stuff on Twitter is to go elsewhere. (Then again, many of us go to Google to search within specific Web sites, since it usually does a better job than the search features within sites themselves.) Did Twitter help Bing with its search feature because it’s working on something even more advanced of its own? Might another shoe drop in the form of Bing’s Twitter search becoming Twitter’s own search feature? Will it let other search companies (no, I’m not thinking of anyone in particular) provide their own Twitter search features?

(Side note: Web 2.0 cohost John Battelle interviewed Twitter’s Ev Williams last night here at the conference. Unless I misheard, Williams said “Scalability today isn’t an issue for Twitter.” Which is an interesting take–I’ve repeatedly seen Mr. Failwhale and his “Too many Tweets!” message while Tweeting about the conference…)

Will the CIA Snoop on Social Networks?

Posted by David Worthington on October 19, 2009 at 8:58 pm

The U.S. Central Intelligence Agency has bought a stake in a company that monitors social media as part of an ongoing clandestine effort by the agency to aggregate content from public sources, Wired is reporting.

The CIA has invested in Visible Technologies, a company that produces technology for search engine marketing for social media. The CIA’s interest in its technology is obvious–the agency needs to keep pace with the latest communications technology.

Over 70 percent of Facebook’s users are located outside of the United States, in over 180 countries. “There are more than 200 non-U.S., non-English-language microblogging Twitter-clone sites today. If the intelligence community ignored that tsunami of real-time information, we’d call them incompetent,” Lewis Shepherd, the former senior technology officer at the Defense Intelligence Agency, told Wired.

The advent of cloud computing raises more concern, because services store data among data centers all around the world. I recently wrote a detailed report about how laws that safeguard your privacy are not the same in every country. If messages pass through a server overseas, does that give the CIA the right to browse the content even if a user is a U.S. citizen?

The CIA is barred by law from domestic spying in the United States, but in the past, the agency has employed creative ways to bypass the law, to hide documents from Congressional review, and to set up an illegal dragnet of domestic communications services. In the last case, Congress gave telecommunications companies immunity from prosecution after it allegedly learned about the spying.

Of course, most folks’ Tweets are public, and even if you don’t share everything with the entire world on Facebook, it’s less private than a phone conversation. Does the notion of the government monitoring social network activity make you nervous?

Twitter, It’s Time to Fix Short URLs Once and For All

Posted by Harry McCracken on September 25, 2009 at 12:26 pm

It’s not a gross exaggeration to say that without short URLs from services such as Bit.ly and TinyURL, Twitter might not have become the sensation that it is. They enable the sharing of interesting links and photos and generally let the service transcend its 140-character limit. But they also bring some major gotchas, such as the possibility of your links breaking if the short URL provider goes out of business or simply loses interest.

Another basic problem with short URLs: They can be dangerous. The very idea behind them is that they’re short (and therefore cryptic) but can redirect you to any URL. But the URLs they redirect to can send you to malware-infested sites–and since you see the short URL rather than the real one, you don’t have the opportunity to inspect the address for tell-tale signs that it’s risky.

Security software kingpin Symantec is understandably interested in short-URL security, and produced this video showing some sleazy ones on Twitter:

If you can see the real URL before you click, there’s a very good chance you’ll figure out it’s not something you want to visit. Which is part of why many third-party Twitter apps (such as Seesmic) let you preview the true URL. Weirdly, Twitter itself only provides this capability in its search.twitter.com feature, via “expand” links (which don’t appear next to all short URLs–you don’t get them with Digg links, for instance).

Seems to me that it would be fairly simple for Twitter to make short URLs a whole lot more useful and a whole lot less insecure. Here, I’ll map out a course of action:

1) Twitter should launch its own URL-shortening feature*. (Currently, it uses Bit.ly as its default service.) It’ll tick off every third-party shortener and probably drive most of them out of business, but the benefits to Twitter users will ultimately be worth it. If Twitter itself controls the short URLs, they’ll work for as long as there’s a Twitter, and the company will gain the ability to make them better than existing ones.

2) It should institute a short-URL expansion feature throughout the site–and instead of making you click an “expand” link, it should autoexpand them so the short link never appears. If users need to take the extra step of clicking to see the real link, they may or may not bother–but if the real one is staring them in the face, many questionable URLs will be manifestly obvious. (And some scammers probably won’t even bother to try and do their dirty work via Twitter.)

3) It should put the real URLs that short URLs point to through a malware-detection feature along the lines of ones that are now standard in Web browsers. If a real URL looks suspicious, Twitter shouldn’t permit it to be turned into a short URL in the first place. (Again, doing this should not only foil malware links that do get through, but should discourage scammers from bothering in the first place.)

*If Twitter is really worried about destroying third-party URL shorteners, it could accomplish most of the above without launching its own service, by launching an API (with malware detection and other enhancements) that other URL shortener can take advantage of. Even if it does create its own service, it needs an API so that third-party Twitter clients can bring all of its goodness to their users.

The above game plan would require some time and money, but if Twitter’s ambition is to be the pulse of the planet, it’s going to be responsible for taking actions that make it harder for the bad guys to screw things up for the good guys. And if the company really has a hundred million bucks to play with, it should throw a little of the dough towards solving this problem once and for all.
