If you look over on The Right you'll find that I've added links for two sites where you can find web comics. If you aren't familiar with them, or are looking for something new these are two really good sources.
If you don't already know, Web Comics are comic strips/books/graphic novels which are posted by their creators. These could be on their personal sites or they could be 'hosted' by a group or publisher. Both Drunk Duck and Top Web Comics have links to dozens of different types of comics. They range from humor strips and single panels to graphic novel length story lines which go on for weeks, if not months. They also cover just about every genre you can find in print comics or on newspapers comics pages. There are even some which don't easily fall into a single genre, mixing several or creating something new.
Some of the artists and writers, often one person is credited with both, are barely above what we used to call 'fannish'. It can be crude and amateurish but often the artist shows promise and you can see her/his abilities improving over the course of the story. Other strips are done by people who are highly accomplished, even well known in the industry for other work. I should also be point out that I believe that some names credited with either art or writing may be pen-names for folks not wanting to be recognized.
Drunk Duck, besides the comics themselves, also has games based on some of the titles and tutorials for folks interested in trying their own hand on doing comics online. You might recognize some of the writers & artists you find here, plus several have published trade paperback editions collecting older strips.
Top Web Comics allows you to create your own list of favorite titles you can check each day, plus allows you to vote for each strip. The Top 100 comics are then posted on the main page, giving the creators even more exposure.
Click on over and check out each site, since you'll find comics original to each. You also should be aware that some of the strips have "adult" themes which goes from graphic violence to profanity to nudity & sexual content.
While you are at it you should also check out the newly designed ComicMix site, where you can find other examples of web comics by folks like John Ostrander, Tim Truman, Mark Wheatly and other. (Warning: Somebody I used to know has something to do with the ComicMix site, but I haven't figured out exactly what it is.)
