The Library of Congress has announced that it will archive every single Twitter post ever written in a new archive.
You can read the Library of Congress's (strangely breathless) blog post about acquiring the Twitter archives here.
Have you ever sent out a “tweet” on the popular Twitter social media service? Congratulations: Your 140 characters or less will now be housed in the Library of Congress.
That’s right. Every public tweet, ever, since Twitter’s inception in March 2006, will be archived digitally at the Library of Congress. That’s a LOT of tweets, by the way: Twitter processes more than 50 million tweets every day, with the total numbering in the billions.
The LoC also took the opportunity to announce that it holds "more than 167 terabytes of web-based information."
(By the way: I don't have much to say about Twitter's announcing that they're selling ads. I figure it'll be unintrusive. I just wish that they'd find a more interesting, innovative business model. As newspapers have learned, advertisements are a fickle mistress. I'm a little concerned that the entire internet as we know it is based on an advertising model.)
