I know, I know. The last thing any of us needs is ANOTHER social network to maintain. I mean, when was the last time you looked at your Google+ account?
Still, I thought I'd give ThisIsMyJam a whirl. Creating and sharing a playlist is a snap. Finding people/organizations to follow is easy (I'm starting with some British music writers and Amanda Palmer). Audio quality is good. And it's 100% free.
I'd be interested in your thoughts about the service.
