Good advice, although I personally disagree with him on the Janus front.

Janus is what got me to switch full time to Vim a few months ago, after having used Vim off and on for over a decade, mainly on the command line or for edits that were to difficult or repetitive to get done in more "friendly" editors/IDEs like TextMate and Visual Studio.

Janus provided just enough familiarity and convenience to make a full-time swap something I could stick with. After a couple of months of this I did basically dump Janus and start managing plugins myself with Pathogen (adding new ones and removing some of the default Janus ones), and customising my config (which is still based on the old Janus config, but extensively modified)
