Don't see anything wrong with being "short" as long as you have a point to make. Don't see anything wrong with posting a meme or photo, as long as you take a few frakking seconds to help us understand what makes it cool enough to warrant a post.

I don't like "walls of text," either. Put some freakin' paragraphs, sub-headings and pictures in there to break it up.

If you don't know how to format a post, learn. It's really not rocket science!
