What systems are out there now that people are using to serve as their comic archive?

hey i just wanted to introduce myself, im a webcomic newbie I am the creator and operator of http://sparkycomics.comicgenesis.com so that means if one of the links is broken its probably my fault. Id love to get some feedback on the site. Im updating and improving on a daily basis getting the kinks out. And i could use all the constructive criticism i can get.
I hope you like it!
