Way back, I was a regular on that site and that is where I actually gained most of my initial reputation. Won several monthly contests. As an reward, I think I accepted a couple CDs, but later opted for the physical books they were offering at the time. Got several of those too. The only problem with the CDs, in my opinion, was that they were much like the site, but at a smaller scale -- needed to wade through weeds to find some gems.
