Rewrites

But there are other types of rewrites. The one most dear to me is the “Don’t Try To Turn A Chair Into A Table” rewrite. It’s the one we committed when we launched the new version of Basecamp a couple of years ago. A full, start-over, everything-is-reimplemented rewrite of Basecamp because we wanted it to do different things.

Starting over allowed us to question the fundamentals of how the application worked and how it was implemented. We were able to make leaps, not just skips.

A chair can indeed be turned into a table with enough effort. Both have four legs, and all you need to do is chop off the back of the chair, and somehow refasten it to the base to extend the surface. Oh, and maybe some new wood to raise the legs up higher. It can be done, but why on earth would you?
