What do you regard as good contents? Everyone have different levels of evaluations. What you might call bad content might be good to another. Do you mean a long essay, maybe 1500 - 3000 words or a short post of 200 - 500 words?

I guess you have a particular set of people you watch out to see them post, or maybe you are keyed to certain tags.

A lot of people create good contents daily and maybe what you need is a content hunter to help you hunt them if you can't find them all yourself.

Give me a reason why my posts aren't good contents and I will give you a reason to vote a good content
