There are levels of "free speech" on the inta net, and I think all three sites (plus the TKR in its prime) are different versions of it. Really depends on the atmosphere of a place. I like Mock because the crime forum is about as up to the minute as you can get for stories of national interest, and there are a handful of people whose takes I enjoy reading. TK is where I go to get my fix of the internet's version of hanging out in the basement and talking about far out shit while blazing up, maaaan. I tried the Haven site and found it too full of tards for my liking, with a couple of notable exceptions like Seph and Iggy. (Don't take it personally, I had the same reaction at most of the sci-fi sites attached to TK) Beauty of the inta net is, there's a place for everyone.
