ComicMix is very much worth checking out if you're a comic book fanboy, the site features free issues of full comic books that you can read online. I was quite impressed with the ease-of-use of the interface with the site (a sample of which is shown above) which allows you to navigate a comic without having to open Adobe Acrobat. I also liked the fact that the first wave of comic books that they're showing are quite diverse in subject matter and style, a good example of this is Munden's Bar #2 which featured some nice artwork by Marc Hempel. Also their comic book news coverage is worth checking out too...
