Apparently Facebook was down for a couple of hours yesterday. They say it was a database glitch, but I'm betting it's because two people poked each other at the exact same time.
The outage apparently caused Facebook addicts to roam the street in tears, shoving photos of themselves in peoples' faces and screaming "DO YOU LIKE THIS? WELL, DO YOU?!?"
There are also scattered reports of Facebook addicts meandering into fields and farming the land.
