Here is list of things I contribute to and/or read on a regular basis. Note: titles are also links even though they aren't blue.

Casey and Andy - Probably my favorite webcomic ever. I would consider this comic a distinctive influence on my work

Homestar Runner - Easily the best webcartoon ever

Coolppedia - I made like half of these pages. [Site has returned, GO.]

Dystopia - Really great mod for the source engine.

Saturday Morning Breakfast Cereal - Arthur reads this.

XKCD - I identify all too well with this comic. Warning: Sometimes contains math humor.

Questionable Content - Occassionally hit-or-miss, but I have actually fallen out of my chair laughing at some of these.
