wondering what other social networks musicians out there use and have success with.. a lot of them are very overrated. i'm the most impressed by soundcloud.
Not sure. These are a few that I frequent from time to time.
http://guitarlogic.org/ Has some good musicians and a lot of tech stuff. This one and Bandmix are the most active that I frequent. It pretty much depends on how much you want to put into them.
Mixposure.com Has a lot of good stuff.
Reverberation .. never had much to do there so far.
