I think part of the success of #linux based operating systems is that they managed to create a nexus for /every/ #FreeSoftware program to distribute itself to interested people, through package repositories and package managers. it's incredibly powerful that you can load up an entire minimum operating system of purely Free Software and then boot up your package manager and go discover more.
I think we need to create something vaguely like that for #FreeCulture to really get it to snowball.
