I also suggest letting your piece "set" or "cool" for a couple of days before hitting the "publish" key. I am often surprised (annoyed, or bored) by extraneous stuff I wrote in a first draft, and glad I read and edited the thing before putting it out there. A little distance goes a long way here (as it does for any writing). Of course, you can always edit once published, but you may have lost a few followers in the interim.
