I've just opened a new site (literally like an hour ago) that uses an existing concept in a sort of new way. The site is
www.fapolicio.us (I know, I'm practically begging Yahoo to sue me). The basic idea can be gleaned by anyone familiar with most social bookmarking sites. However, this is social bookmarking for the Adult web.
All are free to join. All are free to post links. Be creative with your tagging. The more people that post a given site; the higher it ranks for certain tags. The idea is that better sites will be listed by more people and this will bring a sort of meritocracy to the Link List.
I encourage you to join and add your sites. I simply ask that you don't post any manipulative sites or popup hells. If I have to start editing a mysql database to get your links out, I won't be too happy.
I'm also interested in hearing what all the other webmasters here think of this idea. Do you trust the porn-watching public to post and tag the best sites?
