I have always wondered how many people use the stock Janus/maximum-awesome Vim setups? How do people maintain their customizations? (the same questions actually apply to other configuration systems like dotfiles, etc.) The reason I ask is that I've found these projects absolutely great in helping me learn more, discovering new plugins, and putting them all together in a (somewhat) maintenable way. But I've ended up with my own forks. And while I only tweak them every 6months or so, I usually have a hard time rediscovering the improvements that these systems have made in the meanwhile.
