I had the same kind of experience. For me, it started with day after day in late 97 taping Season 1 Win Ben Stein's Money's. Made a full tape's worth. Then, a couple months later, I was doubly blessed with the new season, and my now wife's uncle having access to GSN to tape all the Tic Tac's, Joker's, and eventually all Card Sharks that I wanted. And as I kept taping, I started searching around these parts. Got the Larson shows right way from Connolly (anyone seen him lately, how's he doing now?), and it just grew...
Today, over 1800, I'd guess, counting what's not chronicled. Now, it's true I don't trade much, but it's from my busy-ness as a teacher. During the summer I can tear it up if I want. Meantime, I TiVo stuff, especially as it's airing if I see an episode that just stands out in my book. Taped yesterday's Lingo, for instance, because I loved Chuck's total state of looniness over the weird gameplay that day.
Best part, when I make trades, if there's space left on the tape I get, I use it when I can. And ultimately, I will DVD some more stuff. Just don't know what yet.
And for what I'd do with it all? Hey, I'm just the kind of guy who loves to share, and between some of my friends and my students, there's always something to show. Plus, you never know when you just feel like pulling a show out because you're in the mood to see Tom Kennedy host Price or something...
