So those tweets about what you had for dinner, that movie you hated, and how much you like pumpkin spice lattes are actually worth something!

Twitter went public this morning at the New York Stock Exchange, debuting at $45.10 a share, valuing the social media platform at upwards of $30 billion. Stock symbol? TWTR. Hashtag? #$$$$

Their selling price of $45.10 is 73% higher than their initial public offering of $26 (which they announced, via tweet on Wednesday). The 7-year-old company, which has failed to deliver profits, was one of the most anticipated public debuts this year. Twitter initially had their IPO at $17 – $20 before raising it to $23 – $25 on Monday.

The Wall Street Journal reports that Twitter’s debut is the biggest U.S. technology IPO since Facebook’s IPO of $38 a share in 2012.

Ringing the NYSE bell were some special folks on hand — namely Twitter users — actor Sir Patrick Stewart, nine-year-old Vivienne Harr (who sold lemonade to end child slavery), and the Boston Police department’s Bureau Chief of Public Information Cheryl Fiandaca.

Stewart, who has over 700,000 followers, tweeted his excitement at being included in the event:

Twitter co-founder Jack Dorsey tweeted from the trading floor scene:

Another celebrity tweeted this inquiry last week: (Something a lot of savvy-minded Twitter users may be wondering as well):

And wait for it …

It’s about time someone cashed in on the 140-character joke.
