I once hit the old 2500 FB limit - They were mostly all invites for games, except a few personal and Mudcatters. At one stage, I stopped all FB games, and deleted all 'FBfriends' that I thought were just gamers with whom I had not had various conversations (so they were 'remembered'!) - but I may have accidentally purged a few MCers who didn't say that they were MCers and got 'labeled' (put into a group) as gamers.

I started playing just Castle Age again on FB and started inviting more. I have found many with who I have more in common that just the game, and we comment on each other and I have even found with similar viewpoints on many things, music, politics, science, art, etc.

I also play CA on Myspace, but now that they have 'improved' the interface, I can't easily track down those who don't play and remove them. On FB you can still easily identify, track and remove anyone you don't want.

There is nothing there on any of those sites that I didn't care about hiding, or worry about being out there.
