Twitter (TWTR) finished its first day as a publicly traded company on Thursday with a closing price of $44.90, down from an opening trade of $45.10 but up a cool 73% from its IPO price of $26.

The offering made Twitter's founders and leaders rich. Very rich. Now, if you're one of the company's 230 million users, you helped out, right? So what's your share of the riches?
