i don't see why biz week mentions myspace and friendster first -- facebook whoops friendster's ass as far as #s are concerned, and is gonna be overtaking myspace pretty soon in terms of %returning users/day.

I totally agree. It makes them sound like they don't know what they're talking about. I also thought it was funny that now they're describing these amazing 'niches' that are being worked on when it's been happening for a real long time.
