At least you read a lot of comics. I only read 3 issues in my whole life. I started with a video game based comic book series, Injustice Among Us, and some comic book about Huntress. I actually forgot my Comixology password, so that's why I couldn't read legally.
Should post a picture of your autograph. That sounds awesome. I haven't been to a comic con, but I did went to Anime Expo for the first time. I didn't get any autographs except with Little Kuriboh who is somewhat an official VA.
Holy Jesus! That's a lot of writers and characters. Maybe, your top three would be good. I will edit the OP and add your favorite writers and characters in the OP. I'm glad to see you here.
