Lately, I've been seeing "having said that, ..." or "that being said, ...", a little much in comments and blog posts. Having said that, I'm trying to avoid it myself.
Just noticed that jackowayed below has a variation of it in his comment.
First time I can recall seeing "Dead Simple" is on Posterous. I think we're just used to everything being overly complicated so that anything that's simple is by definition "dead simple". Simple by itself is naked and unsophisticated. Dead simple on the other hand is special.
