I have been reading wikipedia for far longer then I have been editing. Here is a compendium of some topics that I have found especially fascinating. Some of the pages listed here are lists of articles I find myself browsing for long periods of time, but I'll try to list specific favorites from them as well.
I plan on coming back to this list to add more later. Check back soon!
