Well, since Asi said that we could put our own suggestions down in her topic, here's mine:

Something I've noticed that irks me a bit is the layout of people's posts. A lot people combine their posts into one huge paragraph, and everything gets jumbled together and makes it hard to read. I know we don't have a "tab" or "indent" here, but at least start on a new line (if not skipping a line) when going from thought to thought. Long paragraphs get annoying to read after a while, and even more annoying if there's only one paragraph and it's a huge (page-long or more) post.
