Genuine nudists and naturists have a social network to call their very own after an enterprising team set Skinbook up on Ning. Karl Maddox and friends from Manchester set up a forum a while back after coming across a nudist beach in Wales. They lost interest in the project but when they went to delete the space, discovered 247 registered members. Now a social network in its own right and very much in the design mould of Facebook, Skinbook has a 6,000 following and has had 25,000 applicants. Presumably, the unsuccessful 19,000 were just after a bit of free porn. I'm not sure how much money one makes out of such an enterprise but, if you fancy a crack at creating your own web 2.0 niche, then head over to Ning. (via Metro)
