Toooooo many people/sections to list but I'll do a list I guess given as this thread pops up every now and then and I can copy and paste this for later.
In the WWE section aside from the obvious DesoRow, I have really started enjoying Starbuck's posting and know that he'll be up for great discussion at any time if you're willing to put the effort in, Winning One, Brye, Segunda Caida or however you spell their name and TankofRate also are up there.
The chatbox peeps I like would be like Rush, Kiz, Wagg is getting there, DUBCUNT, scrilla, CP, that Wesson ...... and Josh.
Headliner is a jobber and the worst poster on the forum.
My favourite new poster is 8 Pound Gecko and I'm expecting good things from him (I'm predicting 12'er of the year already) and ZigglerMark has jumped out at me recently too.
As for my overall favourite poster on the site, gotta' go with Shepard.
