Don't listen to each reader; listen to them all

In the Private Forum, a member asked the following:

If you've been following a webcomic and you don't like the direction it is taking and eventually it gets to the point where you're not enjoying it and decide to stop reading it, as a good fan should you politely just forget the comic exists or should you tell the creator why you have decided to stop following his/her's work?

I'd like to address this subject from the standpoint of a comics creator, and from that perspective, the answer is clear. The fan is more than welcomed to send the e-mail, but any cartoonist worth his or her salt is going to promptly ignore it.
