Interesting choices, and good thoughts on them. I really like how you and Calumon interact with each other. But if you don't mind, may I make some recommendations? Here's some you two might like:
Irregular Webcomic (lots of puns and complicated physics-based humor, still pretty good, though.)
Darths and Droids (it's basically the first 3 Star Wars films... as portrayed as a tabletop RPG. It's way better than itn sounds.)
Zortic (This one went though a revamp a while back. I still prefer the orginal version, as it's more humorous and full of pop-culture references.)
Melonpool (Another scifi comic with plenty of pop-culture homages)
Zap! (Yet another sci-fi comic, don't be put of by the simple art at the beginning, the story really draws you in.)
Dandy and Company (The adventures of a boy and his dog... and the strange situations they keep getting in to.)
The 10 Doctors (Like Doctor Who? This webcomic mixes together a wide variety of characters thoughout the series run, and makes it work .
Order of the Stick (a comic with stick figures... and a really good story)
The Adventures of Doctor McNinja (Pure awesomeness concentrated... 'nuff said.)
Digger (Beautiful story, art, basically everything about it is excellent.)
