Brad Guigar's Webcomics.com adopts a $30 per year fee for access to (all?) new content and all of the archives. Brigid Alverson has a good write-up of it here. Webcomics.com has been an incredible resource and growing community over the last 12+ months. It'll be interesting to see if this changes works. I certainly wish Guigar luck — if this allows him to put more into the site and keep it growing than of course it's a success.
For what it's worth I'll have more to say about this and ComixTalk and all things webcomics in the days to come.
