Four Horseman of Android Distributions

I've seen a lot of discussion about Android and its various downstream distributions. Many folks are also confused with "security" and "privacy" distros!

I wrote this post (and rant) to clarify what these mean - and how we got to this point. It's a worthy discussion, given the relative stability of these distros.

Please let me know if you have any additional suggestions for the article - I can edit it pretty easily!
