There's another kind of mobile social networking developing – mobile but not on phones. For Microsoft, it's about socializing around music, and it's aimed at the iPod market but will also have some things in common with MySpace music community and iLike in Facebook, which of course are also giant competitors. Stiff competition, but a worthy idea, analysts are saying. "Along with the three new Zune players, including Microsoft's first-ever flash-based model, Microsoft announced a new community site dubbed Zune Social that it will fire up as beta in November," PC World reports. "According to Microsoft, Zune owners can automatically share their current playlists with friends using a Zune-to-Zune Social sync." The syncing involves user profiles called "Zune Cards." Users view each other's Cards and play samples of the Card owner's favorite tunes, which they can then go buy in the Zune MarketPlace online music store.
