Speaking of webcomics. What are your favorites?

While on the topic of webcomics, I’m curious what strips folks read regularly? I have all of mine loaded up in Google Reader (currently one of my favorite toys), and while I’m not necessarily looking for other good strips to add to my lineup, I’m always interested in finding new interesting comics. Some I add to my daily read, some I let slip…

Anyway, here’s my current reading list.

• Order of the Stick
• Sinfest
• Inktank
• Three Panel Soul
• Girl Genius
• Dilbert Daily
• Penny Arcade
• PvPonline
• xkcd

So, got any suggestions of strips I absolutely should read, no matter what?
