Damn Mr. Mo...not deserving of mention here, but thanks all the same.
I'm with you on Straguzzi and would include Picsix and potteryman as those who aren't here anymore (or very seldom). I would also put johnnymo, NL and MMP up there as threads which I seek out.
From a strictly capping/pick perspective I would say DHayes, Josh Daniels, and JB (whereabouts unknown).
The Silent Majority and Atlantic City Jogger provided for many an entertaining post, both gone but not forgotten.
And I would be remiss if I didn't include Harry Begg, allie91258, curtboy, SethS, TeeRed, Al Como, Uncle Lambert, and Richard P....all the same person but has provided lots of laughs over the past few years.
