Ask HN: Difference between running a startup and working for a startup

Is there any article that gives me some insight on the difference between working for a startup and running a startup. FWW, I feel like the exposure to the bleeding edge technologies is limited when you are working for a startup. No founder (atleast I think) wants to try out some thing that is too young. For web-based companies though, I can pretty much guess its mysql people will go for, not bothering about if they require a RDBMS for the startup or not.
