I think each check-in has its own culture. Every-Day-In is about middle of the road; some people cross talk and some don't. That works for me because sometimes I like to/have time to cross talk and sometimes I don't.
Like Suze I've cut back on my web time and have really cut down on my check-ins (I used to be in three; two here and one elsewhere - that got to be insane).
So I generally agree with the others - find one you like, or build your own!
