Most of the webcomics I read are already immensely popular so there's no sense in linking to them here, so instead I'm just going to link to websites of my friends and other fun diversions.

Dollies! - My sister and brother-in-law's universe of characters based off of themselves, UBER CUTE.

Fluff in Brooklyn - The best/only podcast about nothing that I listen to. Well, they do music reviews, but
I listen mostly for the insane conversations and utter hilarity. Plus props for being in Brooklyn.

Alison Wilgus - Lots of cool artwork and a few manga-style comics she made with friends

Plain Stoopid - Webcomic of my friends Geoff and Jessica

Dark Horizons - The only movie news site you'll ever need

Gamespot.com - The only video game site you'll ever need

LoveHKFilm.com - Great website with news and reviews of the latest Hong Kong films

OverheardinNewYork.com - Just what it says, conversations people overhear from places in NYC

NYTimes Metropolitan Diary - Stories New Yorkers write in, usually very funny, occasionally cheesy

Online Etymology Dictionary - Ever wondered the origin of a particular word?

My del.icio.us - Stuff I've bookmarked lately, may contain mature content (I can't think of anything off the top of my head, but I just want to cover my bases).
