The distro-hopping and vanilla installs are the problem imo -- with Linux it is possible to strip your system down to the basic functionality so that you can actually understand everything what's going on and not be surprised. What is so refreshing is to realize that you don't need to pull in some baroque package you don't understand because the part of it you want is just 3 lines of bash and one line in a config file or whatever. But to get there you have to learn how to use the tools.
