BTW another example that comes to mind regarding beginner-friendliness is how long it took to get Rails working with Apache. Before Phusion you were supposed to run your own mongrel cluster or similar fringe solutions - it was insane to ignore the world's most widely installed server. Personally I only started considering Rails production-worthy after mod_rails turned out to be fast and stable. Sure, I can run Thin/nginx or whatever, but I don't want to learn a new server (and wait for it to mature) just so I can use Rails.
