Ask Slashdot: I Want To Get Into Comic Books, But Where Do I Start?

An anonymous reader writes: Hi fellow readers. I don't recall reading many comic books as a kid (mostly because I could not afford them), but of late, I have been considering giving that a shot. I wanted to ask if you had any tips to share. Do I start with paperback editions, or do I jump directly into digital? Also, could you recommend a few good sci-fic comic book series? Thanks in advance!
