I don't find it to be especially powerful for that. This was what was in my Facebook feed just now, at 4:20pm on a Saturday: 6 "has joined the group..." or "has become a fan of..." messages 5 miscellaneous profile updates (added photos, became friends, etc) 4 facebook spam (a facebook ad for facebook ads, "Top Books in Boston, MA network" etc) 1 application message (somebody added a "bumper sticker") My theory is that, since it's the first beautiful Saturday we've had this year people are outside enjoying the weather without bothering to update facebook beforehand. There are probably people going out somewhere tonight, but haven't decided yet and aren't using facebook to figure things out because text messages are way more reliable when everyone is scattered around actually doing things.
