Twitter has formally submitted their paperwork today for that rumored, inevitable IPO. In a tweet posted just minutes ago, the company writes, "We’ve confidentially submitted an S-1 to the SEC for a planned IPO. This Tweet does not constitute an offer of any securities for sale." What's news to us, copyedit-wise, is that "tweet" is supposed to be capitalized. Does that mean reTweet needs a capital? We digress...

It has already been retweeted 6,000 times as of 2:00 PM (PT).

As we noted last month, Twitter execs have been taking meetings with banks for a while now, and they reportedly want a lower profile and less disastrous IPO than Facebook's troubled offering of last year. What that means in the end we can't say, but it sure as hell won't be that low profile, given that our AP alert just buzzed the second they tweeted the news. Or, rather, Tweeted the news.

Then, maybe too cutely, one minute after their announcement they posted this photo saying, "Now, back to work." Wtvr. We all know they're breaking out the champagne and toasting each other's awesomeness on their garden patio right now. #lies
