Newsweek has decided to put Web 2.0 on its cover this week. Is it just me, or does the irrational exuberance of a few years back seem like it’s just around the corner again? I’m as keen to see a return to fun and excitement on the Web as anyone. I just worry that we’re about to see a whole bunch of folks repeat the mistakes of the past. At least this time, it seems that a number of folks are thinking through how to make money on the deal, instead of this “selling a dollar for 90 cents and make it up on volume” silliness we all dealt with the first time through. Tim Leberecht (who I’ve just started reading, thanks to Technorati), has a viewpoint on this, too, recapping the recent thoughts here about whether Web 2.0 can live up to its hype. Check it out. It’s worth the read.
