NickI've been an occasional lurker here, but only joined now.
Some of you already know me from other boards, but I'll still give the detailed collecting interests.
I collect everything sports to some degree. Most of my focus is baseball, both vintage and modern, but I collect other sports as well (with a tiny amount in non-sports cards). I also collect autographs and memorabilia (everything from store model equipment with player names to press pins to bobbleheads to yearbooks/programs to actual game-used equipment).
I collect both raw and graded. I mainly buy graded on line and raw in person.
I'm an Angeleno, and collect the Dodgers, Lakers, and Raiders especially.
In pre-war vintage, I mainly dabble, although I'm slowly working on several of the Goudey sets, Diamond Stars, R312, M116, T206, '40 Play Ball, T218, Goudey Wide Pen Premium, and type cards.
In post-war vintage, I'm working on R423, all the Topps and Bowman major issues, Lake to Lake Braves and Packers, Topps Venezuelans, Kellogg's, Topps Candy Lids, Red Mans (w. or w/o tab), '49 and '60 Leaf, '59-'63 Fleer, OPC, Bell Brands, Morrell Meats, Red Hearts, PCL sets, type cards, and a number of other smaller sets.
In modern cards, I'll mention that I collect Jerry Porter (Raiders WR), autographed cards, game-used cards of retired players, and a number of other things that will get me banned if I talk about them much here. 
I'm not pleased that vintage memorabilia is cut up for cards, but since they're already doing it, I will buy it if I can get it cheaply on the secondary market.
I also focus on HOFers from each sport for autographs and cards.
