Here's another couple of web comics mentioned today at Questionable Content:
Sci-Fi silliness. Over 3000 strips so far, one a day, with no missed days. The artist says he wants to hit 10000 at a minimum, so it won't be disappearing any time soon. I've just started reading at the beginning, and it looks promising. Nothing even PG so far, and probably safe to open in an office.

Manga in high style, from the glimpses I got between server crashes. I have no clue what the story is about due to the server crashes, but the art I saw was impressive.

Others I've mentioned before
Consider this a reminder that QC (http://questionablecontent.net/) is worth watching... do start near the beginning or the most recent strips won't make sense at all. Be sure to watch out for the daily specials.
And, having now read about half the story so far, I can say that Girly (http://go-girly.com/) is not actually as NC-17 as its advertisers are on average, but it certainly rates a strong R and does feature a complete lack of ambiguity about the hero and her sidekick's sexual preferences. And kittens. And a twisted genius veterinarian.
Also, today's XKCD is a riot. http://xkcd.com/469/
A recent XKCD strip (http://www.xkcd.com/463/) was featured as a summary of problems with Diebold (now operating under some other name) voting machines in Ohio on the infamous RISKS-L list (http://catless.ncl.ac.uk/Risks/25.29.html#subj3.1). Apparently there was anti-virus software on the voting machines!?
