Great article, Steve. More often than I care to say, I've come across old code and asked myself what cretin wrote this crap, only to discover that it was me.

This article reminds me of one of the test programming websites (I think its CodeKata) that actually encourages you to come to their website, take one of the short problems, solve it. Then a week or so later go back and solve the same problem again, but in a different way. It really is worth your time.
