People don’t have these kinds of conversations anymore, because Facebook is the biggest website on the Internet. (You had a nice run, Google.) On Thursday, Mark Zuckerberg announced in a rare Note on his profile page that his social network had finally hit the incomprehensible one billion user mark. (One billion! ) Attached to the bottom of the note — which is kinda weird and includes the churchy-sounding phrase "Today, we honor this tradition " — there’s a little video. It’s Facebook’s first ever ad, one that probably cost about a million dollars to make and it finally answers that nagging question: What is Facebook? Ever seen a chair? Facebook is kind of like a chair."
