Recommended comics that you can read over the web:

Questionable Content : or QC, for short, as fans call it. I would recommend reading from the beginning. Things may not make much sense unless you do so. There’s a fan community here. There is a wikipedia article on QC, here.

Penny Arcade: Geeky comic, specifically will make sense to you if you’ve been a video-game addict sometime in the past (or are!)
Must-Reads:

• I Have The Power

Bunny: One-liner comics. Try reading the first few to let the context sink in.

Dilbert (by Scott Adams)
Must-Reads:

• The Employee Rationalizer
• The Knowledge Transfer

Everybody Loves Eric Raymond: Well, if you haven’t heard of what ‘Eric Raymond’ is, in that title - I suggest you first read about him a bit… . Or well, just read this particular one and you’ll get the hint.
Must-Reads:

• Bruce Perens Dead
• Linux Doomsday(you know what … read this for some context…)
