I tend to entertain the notion that anyone posting publicly isn't posting solely for their own indulgence but to others' benefit as well.

insofar as making stuff goes, especially art, I think there are widely held views that it either comes easy to you, or you don't do at all. It doesn't occur to some people that to be good at something (even something "fun") you have to work at it and put in time that decidedly isn't fun.
