I went through my Google Reader shares to find a blog or blogs you should all be reading, and noticed that most of the items I share are from webcomics. And so. Here are my favorite webcomic sites AND (BONUS!) links to some of my favorite individual comics. You probably read all of these already but maybe you don't, and if you don't, well...you should. So there.
Dinosaur Comics, obviously
Cowbirds in Love (thank you to srah for this one)
A Softer World
pictures for sad children
Hark a Vagrant
Stuff No One Told Me
Married to the Sea
Calvin & Hobbes, always and forever
PS: If you're not reading Hyperbole and a Half (actually, you all are probably reading it so disregard what I'm about to say),there can only be one reason and that one reason is apparently you don't like laughter WHAT IS WRONG WITH YOU? This is one of my favorites.
