Sp! Magazine is for everyone who self publishes. A lot of people think it's only for print comics, it's not. It covers comic and book self publishers and small publishers, digital and web comics, independant musicians, filmmakers and artists, and would consider other things as well.
It's free to download. Here's a link to the current issue: http://www.selfpubmag.com/downloads/entry/free-downloads/self-publisher/self-publisher_7.htm
It has a feature on handmade comics, various interviews with publishers and reviews.
Older issues available as well.
