What do you do when you've just rung the Nasdaq bell at the opening of trading on the day your stock is listed? If you're Mark Zuckerberg, you update your Facebook page, of course.
Who else, really, could post this one: "Mark Zuckerberg just listed a company on NASDAQ." And he tagged five others with him -- Chris Cox, Cipora Herman, Dave Kling, David Ebersman and Sheryl Sandberg.
It hit right as he was marking the open of trading. And he's already received 300 likes and 22 comments on his "recent activity."

[Updated, 8:50 a.m. May 18: Amid the ovations and congratulations, there was also some speculation about what might have been for Zuckerberg if Facebook had never been.
On Twitter, @raffeg, lamenting he was the one who started Facebook today, mused, "Wonder how much Mark Zuckerberg would be worth today had he stayed at Harvard and got his degree?"
Something to think about as we report on how bleak the job market is for today's graduates.]
