This is getting a bit tiresome. Tiresome to hear about, tiresome to watch, and certainly tiresome to think about. At a gut level I think this isn't the last contest for ownership of something with debatable value. 500,000,000 sets of eyeballs have quite a bit of potential, but what guarantee is there of revenue? Facebook, like Paris Hilton, is popular for being popular. Why is Facebook valuable? No one can say. This is lost on just about everyone.
I suppose I could have just noted that it would be nice if they'd do something worth talking about once in a while instead of getting sued at an interval.
