I didn't, because I knew if you ever clicked Buzz you'd been linked to other identities. And Wave was pointless. It's just that I never had myspace or facebook and even tumblr isn't really worth it. I wonder if you use different platforms for different people or identities - but your tumblr is like LJ. See, I have goodreads and flickr, these are very different things to me, very specific. All other platforms - if I don't talk with my contacts in one, why would I in another etc.. If I don't meet like-minded people on LJ where there is fannish content, why would I on FB where you only say "I like".
