> You typically don't have the opportunity to do that in a startup, because you have to focus on the immediate business needs and on staying alive rather than on pushing the state of the art forwards. "Good enough" has to be good enough in a startup.

Interesting. That's something you don't often hear... but it makes a ton of sense to me. I've only worked in academia and one mid-size corp, so startups are kind of a different world for me. :)
