One of my favorite authors, Terry Pratchett, said that to be a good writer you must read extensively outside and inside your genre. I think this is very good advice.
Now, our genre is webcomics, and I know we all probably read eachothers and our own non comic genesis favorites, but what about outside our genres? Here's some some random things that were useful to me.
Pretty much anything on eZine. Ezine is place where people publish their articles for free and then advertised whatever product/service they have. I have found that the sections on both selling and romance provide and endless supply of ideas. It is not hard for me to say, "one of my characters might do that."
Various Podcasts. My comic centers on religion, so I listen to a lot of preachers/teachers. I try to challenge myself to listen to guys that I don't agree with or like (I have a degree in Theology), because it provides great foil for either the beliefs of my characters or just plain old satire fodder. Mark Driscoll is getting spoofed in my comic in January.
Blogs. Blogs. Blogs. I think I have gotten at least three or four good ideas from reading random blogs on the internet. I am becoming far less discriminating it what I put on my list to read.
What random, non-comic related, literture has given any of you guys good ideas?
