I think it's something you can do once.
The "buy a football club" website (Brought up by you IRC DJKZ

), which I think is a similar thing...
They raised enough to buy into my local team strangely enough. For the first time ever they got to Wembley - something to do with the FA Cup and lower division teams.
So for a first year result it's been brilliant. (I was very surprised the football website thing got anywhere at all. I'm pleased they do so well)
Are there any others? I don't know if there is a rival "buy a club" website. If there isn't them it suggests the original moped up all of those who would do it which wouldn't surprise me.
The idea strikes me as a novelty and don't think it will be repeated or endure.... but then again I didn't give the footie website a hope in hell
