Twitter has announced it’s going public.

And it did so in a tweet.

It’s the most hotly anticipated initial public offering since Facebook’s IPO.

Twitter says it has submitted an S-1 form to the Securities and Exchange Commisssion. That’s a financial document U.S companies file as part of the formal IPO process.

Now analysts will hone in on Twitter to see if it avoids the pitfalls that dogged Facebook’s bungled IPO which many saw as ill-timed. That stock was priced at $38 a share but plunged after Nasdaq computer glitches delayed trading in May of 2012.

The stock price only recovered this past July.
