Learning by Shipping – this reminds me of the idea behind “Crossing the Chasm”. Early adaptors use a product in ways they find useful and maybe in ways the original maker didn’t even think of. Different market segments use products in different ways often. I might be (reasonably) happy to compile and manually install open source software, but 99% of people won’t, and that’s one major reason they don’t use Linux or anything but Windows/Mac OS.
