Business-oriented social networks for musicians are an area I haven't covered in a while. A variety of new networks and platforms are emerging and today I'd like to point you to three business-oriented social networks that are worth knowing about. Gigmor connects musicians with compatible musicians and also uses that matchmaking process to help industry people find compatible musicians. AAMPP adds fans to the industry mix along with a variety of tools including ecommerce. Jammcard is a mobile social network for connecting with others by sharing Jammcards.
