I am extremely adept and comfortable with PHP. I've been using it for years. I'm learning python, but I'm still deciding if I'll need to learn rails or not. Is the time it'd take me to learn rails, really saving me time in the long run? I can do pretty much anything in PHP that could be done in rails. I'll still look into it though. I'm not one to jump on a band wagon, but masses of people don't move themselves by just themselves... not all the time.
