I worked in a bookstore for almost 10 years and I got into comics during that time. We would get all of the new comics on Wednesdays and I would pull for subscribers and I just got sucked in. Lady Pendragon was the first comic I bought. The majority of my comics are from 1996-2006. I got back into comics a few months ago and have been buying older stuff to complete parts of my collection as well as newer stuff that looks interesting.
I am a fan of Image (old school stuff), Broadsword Comics, Chaos, Maximum Press, Awesome, Top Cow, Avatar, CrossGen, Wildstorm, Hyperwerks, Aspen, Sirius, Zenescope and many others.
I have started several Facebook pages dedicated to comics as well:
Amazing Female Comic Book Characters - a page dedicated to characters like Lady Death, Witchblade, Purgatori, Lady Mechanika, Aspen Matthews, Tarot, Vampirella and so many more. Mostly dedicated to female characters from Image and more independent publishers.
Chaos Comic Fan - pictures, information, large community of people sharing their collections.
Amazing Comic Books - this page is newer and not as established yet
Check me out on Pinterest too. Comic art is one of my other passions.
