just dont go to the porno star pages, and errr youl be ok. There's a very healthy techno network on there, techno groups etc etc. Ive personally found it one of the best free networking tools a person could wish to have. Ive found great new music through it, had tracks signed to labels from hooking up with people on there, sorted out remix swaps etc etc
just dont presume its going to save a persons music career straight off and you'l be ok with it i think
certainly better than NOT having it
