I picked up on webcomics relatively recently. You tend to see certain names mentioned as the "must read classics" of the genre but I'm afraid that Sluggy Freelance and El Goonish Shive have always left me stone cold. I suppose my comic reading habits come from reading print comics like Doonesbury and Dilbert, or the truly brilliant "Maggie's Farm" in the 80s - surely the best of Steve Bell's work. I'm always attracted to good art, and Liberty Meadows is seriously good art apart from anything else.
Really though, print comics have to be good enough to get printed and that sets the bar while webcomics don't. Plus I don't play computer games, never learnt, nor do I have any real connection to the whole D and D thing, so that doesn't work for me.
So DoA works for me because I recognise the humour, if not particularly the American college setting; the other Walky ones, I've never taken to. GWS, I'm losing interest in as it becomes increasingly wrapped up in politically correct agenda-pushing and the characters become less recognisable and increasingly 2-D. Girl Genius is good, so inventive, very good-looking and the Jagers are a wonderful joke.
