Several reasons:
First, I am in deep financial trouble and as a result it is impossible to find a way to continue to pay for the site at this time. Second, I mentioned not too long ago that I was loosing my enthusiasm for the site. I simply don't feel like taking the time to update it anymore, or to do anything else with it for that matter. Third, running this site is beginning to wear me down. With oodles of other TWC sites opening all the time, its gone from something I do for fun to something more like a competition. Its just not the environment that I want to run a site in.
