I'm very impressed with Fred's work on Megatokyo right now. The last part of the story arc was simply amazing, concerning both the expressiveness of the art and the simplicity and, similarly, the expressiveness of the dialogue. Within the last two weeks I got really hooked on the story arc.
So I decided to buy his comic books as well, since he's giving the world an excellent, free webcomic which updates regularly three times a week, which really should be supported as much as possible.
Plus, I want to reread the comic to understand the overall story better, and I really won't reread 800 pages on the web.
