I think you all have missed the point; it's not technical quality that matter to most viewers--it's whether the like the subject matter and that it ressonates with them somehow.  People do this for a hobby and want to share their work with people, many are just happy to share their pictures and don't care if people them.  Look at the stuff people post on Facebook, the images are not great works of art--some are really terrible--but people like them for whatever reason.  Sometimes the more lurid, the more tintilating the more people will like something. . .

My mother used to say, if you don't have something good to say, don't say anything at all.  If I spend a lot of time working on a picture and someone doesn't like it--I didn't make it for them--I made it for me.  They are not my employer, they are not paying me for an assignment, it is not necessary that everyone likes what I do.  It is hurtful if people disparage your work.  I don't post images for "constructive criticism"--I post them because I want to share and if it happens that some people like what I have done I feel good.

It's sad but true, my earlier images when posted on some sites were very popular and were very simple and not very technically acomplished--those are the images people like best.  I don't understand it--I'd like them to like my current artwork that much, but they don't.  So I do it to please me and don't worry about it.  At times I have lost contests to people who have little technical skills, but have the most lurid, most eye catching content--you figure it out, I can't.
