I started using a couple of new social networking sites recently; please feel free to add/friend/couple/join/borg/whatever with me on them should you also be using them.
(Edit: Skud has a good post on attending shows which is where I learned about Sonic Living.)
I’m also looking at GoMiso — anybody using that? Seems to have a lot of overlap with GetGlue…
I should also mention that, as always, a bunch of social networking sites that I participate in, to one degree or another, can be found on the social page.
