That probably sounded snarky, and I apologize. I guess my point was that these very simple things keep getting reinvented time and time again.
Awesome concept. It is absolutely worth writing about again and a great idea for a blog entry. I also agree that everybody with a startup who isn't break-even yet should be doing this. It's such a simple and trivial thing, yet so immensely powerful. Part of the problem with such simple and powerful advice, as I just demonstrated, is that people too easily discount it because it sounds facile.
