Guys and ladies, I may have mentioned it before, but I really think you all should start reading Schlock Mercenary. It's by far my favorite webcomic, and I think you will enjoy it too.
There's a huge archive, and you can start reading at any chapter, but I'd start with the very first chapter - the art is a little rough, but the humor and story is worth it. It also nicely shows how much growth there is for the cartoonist.
What webcomics do you all like?
I can't say if this are webcomics but i do like to read mangas. I don't have any favorite though.
