I think short posts can be as valuable as long ones with the right content. I'll often post a step by step recipe with photos, a short blurb about a place I want to share with others, or a paragraph or two about why a photograph or color challenge inspired me.

Short posts shouldn't get the short end of the stick just for being short. A lot of words isn't the only thing that gives a post value.

I think the real value is in community! When a post generates discussion I think it is much more valuable than just upvotes!
