Seeing mtov‘s post, Truck-Factor reminded me that many of the apps I’ve used regularly for years are susceptible to a small number of buses (I prefer “Bus Factor” to “Truck Factor).

My most-used apps, typically, are these…

Each of these is developed by a very small team, sometimes by only one person. I don’t really worry about this. They’ve all been around a long time and the developers are active and reliable. While I’d disappointed if any of them were to go away (for bus or other reasons), I wouldn’t be lost. It may sound cold, but I’d just use something else.
