Conventions are an important part of many webcomic business models, but with more and more cons popping up every year, it's hard to know where to spend your time and resources promoting your work. In this thread, we can post personal experiences and information on conventions, which are good, which are bad, which cater to webcomics creators and which don't and so on.
I'll start off with a site called Webcomic Marketing with reviews conventions from a vendor's point of view, mostly located along the United States' West Coast. This site also seems to have other valuable information about the business.Webcomic Marketing
I'll try to update this post as often as possible with more links, info and hopefully comprehensive convention calendar info.
This thread is intended as a resource and discussion board focused on vendors, artists and guests rather than attendees.
