> Linux distros are a fantastic example of this. It's easy enough to create a viable linux distro that there are 5+ popular ones, and if you don't like those there are 10+ less popular ones which are perfectly viable and reasonable choices for an OS.

But isn't this the same as all the Chromium/Firefox forks? I mean I understand they aren't as popular as the major players but you could say the same about all the Linux distributions compared to Windows or OS X.
