If you read comic books on a regular or semi-regular basis, what is it about the medium that makes it special? Why do you find time and set aside money for it when there are a lot more cheaper forms of entertainment out there? What makes comics interesting to you, personally? What do comics give you that other forms of entertainment can't?
If we can get enough answers, maybe we can come up with comics' USP or unique selling proposition.
These are my webcomics!
