Now that the link is behind us, who else here reads OotS? I think it's a great webcomic, on par with xkcd for sure. Considering that most of the webcomics I read (C&H, xkcd, PA) aren't really plot-focused, it makes a good counterpoint to that.
I'm not sure what the spoiler policy is for webcomics, so I'm just going to state this rather plainly:
Plot details follow, discussion of current and past arcs follow. You are warned.
(Exception: Some of us haven't read the published-only books, so maybe those still deserve tags.)
