Probably not a keen interest for most - yet it is a critical function of your bike for the wheels to be true and tight.
A broken spoke is a common enough occurence that the skill to fix it might save you a bit of cash, or an extended time off your bike. But for me, the biggest upset would be to dispose of the wheel because the time and effort (or expense) to repair it is not worth it. A symptom of our consumer society, and one I want to reduce.
It takes a skilled wheel builder about an hour to build one from scratch. So it is not overwhelming to do this. Getting a wheel true is about 10 minutes of this.
