Twitter made public its IPO filing with the SEC today. Buried in the document is the following letter from the company to prospective investors:

LETTER FROM @TWITTER

Twitter was born on March 21, 2006 with just 24 characters:

just setting up my twttr

— Jack Dorsey (@jack) March 21, 2006

We started with a simple idea: share what you’re doing, 140 characters at a time. People took that idea and strengthened it by using @names to have public conversations, #hashtags to organize movements, and Retweets to spread news around the world. Twitter represents a service shaped by the people, for the people.

The mission we serve as Twitter, Inc. is to give everyone the power to create and share ideas and information instantly without barriers. Our business and revenue will always follow that mission in ways that improve–and do not detract from–a free and global conversation.

Thank you for supporting us through your Tweets, your business, and now, your potential ownership of this service we continue to build with you.

Yours,

@twitter
