What qualifies as a web comic? Something that's available on the web, or started on the web, or something that's exclusively on the web?

I personally like Liberty Meadows, but it hasn't been in syndication for a while. (new issue in comic book form recently, but that's it.) There are, however, a couple hundred strips that got censored online.

You can also get issues of Calvin and Hobbes from 11 years ago.
