This is but a handful of data points, but a lot of the rumblings I've heard about this whole trend have been coming from lawyers who take a specific interest in protecting free speech. This includes Marc Randazza, who was mentioned in the article. This also includes Ken White at Popehat, who has an entire tag devoted to IsAnybodyDown (a knockoff of Moore's site that added more crimes into the bargain). There's definite danger of a badly-drafted law going over the line, but it seems that it's possible to prevent the stalker-enabling crap on these sites without damaging actual speech.
