porcupine: in any thread about dogs or sex. (but not both.)
SPOOFE: Any thread about Star Wars, and probably Star Trek, too.
Coldfire: Most threads about Europe or current events.
Esprix, matt_mcl: Any thread even remotely connected to homosexuality (this one was kind of obvious).
Ruffian: Any thread about horses.
Myself (i.e., the OP): any thread about guns or the national media. Most threads about feminism, some threads about sex.
lieu - in any thread about pee or poop
I forgot -
Qadgop the Mercotan - anything about medicine or LOTR.
**scout1222 and I ** will be found in those same scatological threads lieu frequents.
Hello Again will also appear in horse-related threads
Anthracite: Coal, as one might guess.
tomndebb and Polycarp: Threads with a theological bent. (At least the good ones.)
I myself will always appear in a thread about cricket.
Whoda thunk my name would turn up here?!?
I’m also partial to weight-loss themed threads.
This could be more of a game. What type of thread would I normally be found in?
And don’t forget any thread where my name is specifically mentioned. 
Esprix
Eve will be in threads about classic actors and actresses… and cows.
CrankyAsAnOldMan will be in ones about books and humanitarian issues.
Scout1222 and GazelleFromHell will be in the running threads.
Bad Astronomer, appropriately enough, turns up in a lot of GQ astronomy-related threads.
Well, I always wear a trench coat.
Chronos shows up in all those astro/quantum physics threads that make my head spin.
mtgman shows up, predictably enough, in all the Magic: The Gathering threads.
SPOOFE shows up in the PC/Mac debates, as does Yosemitebabe, IIRC.
And handy, of course, shows up in every thread outside of the pit.
dorkusmalorkusmafia will always show up when there are strange things afoot.
Like getting bowl haircuts and overall silliness.
Now THAT’S funny!
For a Trekker.
Anything Trek-related–especially re Enterprise–will feature NoClueBoy, Achernar, Kn*ckers, carnivorousplant, Tars Tarkas, Aesiron, terrifel, me --and sometimes Chuck Forbin, OpalCat, tarragon918, raisinbread, Bryan Ekers , and more.
(Sorry if I’ve left someone out inadvertently.
I’ll also show up in most threads about college students or instructors.
Scotticher will always show up in any thread where someone needs a hug, a prayer or congratulations. (She’s such a sweetie!)
I mostly stalk Rue DeDay, and I tend to hang in silly, light, marginally brainless threads. I don’t think I’ve ever posted in GD, and I rarely read there. I come here to relax and schmooze.
His4ever in the religious threads? :eek:
Ben nearly always shows up in threads regarding evolution, most especially ones that debate it versus creationism. I’ve seen at least a few of his threads turn into EvsC debates by his very presence, even though he was speaking of something different.
Eve in anything mentioning old movies! I gravitate towards those as well, whether I post or not.
