If you want your business to succeed, you need to have multiple edges against the competition. Simply using what other people are using isn't going to give you a technological edge. Look at Paul Graham with Viaweb. He used lisp because it gave him a significant advantage against other players stuck with C++. Or Jane Street, started by three ex-Susquehanna guys using OCaml. There's a lot of technology that isn't boring that also isn't unstable either. These are technologies that probably should be more boring at this point (Common Lisp, Haskell, OCaml, Scala) but are rock solid and stable. These are the kind of technologies you should be using. On the otherhand, if all your "tech" start-up is doing is running a CRUD website, it probably doesn't matter what you're using.
