But that brings us back to mbillie and "if <x> were so great, everyone would already use/do <x>". Does popularity necessarily imply superiority? Adoption just means it's easy for anyone to get aboard. But that doesn't mean it's implicitly good, in any other way. Worse is better works, for example, if one option is more approachable than the other. Decentralization is good, as a rule of the thumb. Not having everyone on the same network, but having the ability to set up your own network or service based on the technology, is a good thing. Why would you want to have everyone on the same network? Networks are often topic-related. For example Freenode for programming-related topics. Minecraft is pretty focused on EsperNet. Quakenet used to be the place to online gaming. This is usefull and good, since communities sort themselves by interest, views, tools or what have you, by default. So why not encourage self-sustainability through means of decentralization?
