If you want geeky humor with enough bitterness to choke a small horse — or an elephant for that matter, Something Positive is the webcomic for you. It tells the tale of the oft-down-on-his-luck Davan Macintire and his friends; their trials and tribulations, all with a sort of depressed, but humorous, cynicism.
I found this comic about a month ago, and promptly read the entire archives, sacrificing my workplace efficiency by about 80%. The first comic is a bit more abrasive than many of the others, so I’ve linked a more typical example of the strip as well.
The artwork is always high quality, and the comic is updated just about every day. So, go check it out.
