I think everybody kind of stalks their "favorite 'Downers" so to speak... I mean the people whose posts you most enjoy. Nothing sinister, of course.
I've recently started stalking Eomer of the Rohirrim. His tricksy appearance being so hard to pin down, I thought to read more of his posts and see what I could learn, which brought me to THIS thread, coincidentally.
I follow Keeper of Dol Goldor around, because I've spent 16 years trying to figure out how his mind works, and I still can't figure it out. I even know where he lives! Mwahahahahaha. And his mother's maiden name. Mwahahahahahaha. Actually, the fact that he's my brother and I live with him (most of the time) and have the same mother... kind of negates the stalker-creepiness level.
As for others I follow around occasionally, The Saucepan Man, HerenIstarion, I used to follow LePetitCheaux a lot, but now we're rarely on at the same time... Once in awhile, if I see that the "Newest Member" is on, I'll follow them around and see what they get up to.

Edit: yes, Eomer, sleep easy once again, knowing that it is I, and that my sole aim is to make sure that when Biff falls asleep, you don't remove the straight jacket.
