So quick background: I'm a recent CS graduate, and have some limited experience working on projects in school, but not much outside of that. I'm planning to start my own startup, essentially it would be an "AirBNB for ---", meaning it would be a platform for a type of peer to peer service. What do you guys think is the best language and framework for this purpose? I was going to start with Python because that's what I/we used for a school project, but I wanted to get some suggestions from more experienced developers before I commit.
