I've been talking with a friend of a friend about perhaps being "the techie" of her new social networking site. She has a business background so she has no language biases one way or another, although she has been involved in the business aspects of launching websites in the past, so she doesn't have any experience with Rails.
From what I've gleaned from her, she doesn't want to do anything technically difficult or groundbreaking. Assuming that I want to persuade her to use Rails, what arguments should I use? OR, perhaps social networking websites are a "solved" problem, and the language used doesn't really matter?
