I also wanted to add that these sites aren't really connected to each other. I know that some of them are run by the same people (NatalieCoughlin.us + MPhelps.us, the SwimStars sites, and some others I can't recall right now), but the majority are all run by different people.
If the swimmers decide to get involved with their fansite, as with MissKaitlin.net and BrendanHansenOnline.com, then I think the site turns away from being simply a "fansite" to something else - it's not quite an official, but it's also not a fansite anymore.
