Granted Joel is taking about a wholesale rewrite of proven / established code. Code and has had had the advantage of time.

Personally, I end up rewriting parts of my code often. It usually takes a mile for me to find exactly the right way it should be based on how are people use it.

You absolutely should rewrite prototypes, and re-factor important chunks of code. I rewrote something 3 times today, it was better each time.

At the same time you should be wary…
