I've said it before in reference to those "favorite poster"-type threads, but it's apropos in this situation, too. Though I think "exclusive/clique-y" is appropriate enough, it could also be described as a popularity contest. In any event, under any name, threads of this nature leave some of those who aren't mentioned feeling excluded and/or with their feelings hurt.
This is in response to TRBL's question, not an admission of my own feelings. Haha, I already know where I stand, and I'm good with it. No one else has to agree with my assessment.
Also, I second SL's advice. There's also a non-FB board as well.
