Well, I can only speak for myself but I like to see whatever people want to upload. If it's an image that you've made, ask yourself the questions "Am I proud of what I've created? Do I want to show this to other people?" If the answers are "yes", then post it.
This is what it says in the Forum Rules:
Correct use of the Community Gallery: Please avoid flooding the gallery with large quantities of similar pictures and/or photographs. This rule is mainly aimed at stopping the holiday snaps plague which threatens to bury us all. This is not to say that interesting photos of everyday things is wrong, but please try make make sure they represent an interesting pose, enticing closeless, or something else special.
