GPS: While surfing I stumbled upon an article that I found very interesting. It has a lot of meat (real useful content) to it, which was unexpected given the title.

DKF - Good page, and I agree with it 100% both as a software engineer and as a Tcl developer. Now, what other Wiki pages can we link this one in with?
KPV - Interesting page but I disagree. Software development has many aspects including new features, bug fixes, refactoring, etc. Unfortunately you only have a limited amount of resources and time, and you have to balance all those factors. As Joel Spolsky writes in the excellent essay Hard-assed Bug Fixin' [L1 ]
Fixing bugs is only important when the value of having the bug fixed exceeds the cost of fixing it.
