Most hobbyists (or low-budget users) who use raid other than motherboard fakeraid will choose Linux md raid. It may well be that most users of md raid /are/ hobby or low-budget users. But your implication - that professionals don't use md raid - is completely wrong. It's more likely that it is hobby users that discuss these sorts of things - professionals just pay the money that the server manufacturer asks for its supported disks, since paying that is cheaper than spending time discussing things. I know I mostly follow lists like this in my free time (as a hobbiest) rather than in work time (as a professional).
