D-Man vs. Lord Sidious - The popular favorite, with good reason. You can do no wrong voting for this one. Sidious did a lot to lock himself in as a hardcore authority figure to newer posters around that time, and so seeing him come apart at the seams was a breakthrough or something. Oh, did I mention it's got D-Man throwing down, which is almost always good fun?
IrishCanadian25 vs. Lord Sidious - Underrated a bit, but remember the Board Room leaks.
GD & Coco vs. Deej - An masterfully crafted vivisection. GD and Coco should be in show business together with the seamless chemistry they demonstrate here. Top contender for my vote.
Coco vs. Ferbian - Ferbian doesn't allow a feud to grow out of control.
fromthesouth vs. Muslims - True to his posting style, he never let the Muslims get a word in.
Macca vs. Sully - All I'm saying is they made The Prison more popular than most any other time I can recall this year.
The Game Rage vs. The World - Rage is a great example as to why some people need to realize their dependance on this place in unhealthy and that they need to seek help. Really, what a fucking meltdown that was. Not really much of a feud, though.
The Doctor vs. Vagina - lulz
Coco vs. It's Damn Real - Way too short, but what's there is almost entirely golden.
TheOneBigWill vs. Luther_Hull - Luther_Hull vs anyone is going to get some good moments, so perhaps I need a few examples of why this particular feud is anything special.
shattered dreams vs. All Wrestling Posters - I shake my head at this nomination because I think it's doing more harm than lulz for the most part.
Furyof5 vs. Honesty - My thing with him was never about his honesty, or lack thereof. I was only ever annoyed by his attitude at times.
tdigle vs. Via Armbar - Oh mama. Most all these other feuds ended, but this one burns to this day. A true battle of the heavyweights. Not sure when this started; I think it was part of the fallout of Armbar vs CB/Profit. Anyway, if this feud doesn't win, it's very likely that it will carry on to be nominated next year.
Becker vs. xfearbefore - This is one of two that I missed.
TM vs. Privacy - This is the more well known and talked about one of two that I missed. All I know about it is something about him having people's pictures and an address or two. All I know about the guy is he repped me once for being the only person to reply to his AFI thread.
I haven't voted yet, so if some of you wish to sway me either way with bits of evidence/links, please feel free to make your case.
