I highly disagree that PHP has more quality information available than Ruby on Rails. Any time I've ever looked for anything on PHP all I get is ExpertsExchange quality (with the occasional gem on Stack Overflow), but a search for nearly any problem in Rails turns up a multitude of amazing blog posts, Google Groups posts, or gems that solve my exact problem. Failing that, IRC (or just digging through Ruby code which is easier to read than almost any language I have worked with) has been very helpful.
