The advantage of posting late to these sorts of threads is that you get to steal other people's lists for yourself. That being said, I'm certain I'll miss a few people, and I hope they don't take the omission as an indication of disinterest. I really follow threads, not people, most of the time (unless someone gets banned) and I find that most people have something interesting to say in the right context.
Town Heretic (who doesn't like him?)
WandererInFog (one of my favorite conservative voices around here)
Son of Jack
Kmoney
Wizard of Oz
Granite
allsmiles (takes on religion on its own terms)
EMETH
nicholsmom (when she's around. We don't agree much, but it's still a fruitful discussion)
Assuranceagent (another good conservative)
cattyfan
TomO (entertaining and insightful)
zoo22
chair (I really appreciate his perspective)
Traditio (usually wrong, but usually entertaining)
Johana (not around nearly enough)
Ktoyou
chickenman
fool
Gerald
The Barbarian
Evoken
Spitfire
annabenedetti
MaryContrary
chatmaggot
One Eyed Jack
andyc
ThePhy
GeneCosta
Cracked
Tyrathca
HappyCetacean (She's so much more knowledgeable than I am about science)
Persephone
Memento Mori
...
This is really turning out to be a list of everyone. Really, there are only a few people around here that I don't find that interesting. Mostly, I just ignore them. So really, the way to know if I find someone worth following is to see who I respond to in the threads.
