I know this is a ruby forum but thought I would ask ehre since Ruby doesnt seem as popular as PHP.

From what I read one my of my favorite web apps Basecamp is developed with Ruby On Rails.. so I'm trying to decide if I want to learn this or PHP.. can anyone give me an idea on why someone would pick one over the other? I notice how fast and responsive Basecamp is.. not sure if thats because of how it was developed or something else.. but was just curious what some of you thought here

Thanks!
