Exit strategy is an element of startups designed to scale rather than those intended as hobbies or lifestyle businesses.

Startups which scale is what Ycombinator is looking for and therefore of interest to many HN readers.

I think there are many other factors that will attribute to scaling and growth beside the exit strategy.

I completely agree. Exit strategy becomes more important once you start taking other people's money. Something which occurs with high frequency among startups.
