I don't think the two are mutually exclusive (see PG's essay about narrow and deep, applied to Google, to Microsoft, etc.)- I also remember reading an early Facebook employee's note about how Facebook had to start out serving college students specifically before they could go on to serve everybody, and how if they had tried to serve everybody from the start, they'd probably have failed.

It may be that the path to universality is paved with niches. You can't write a book about everything. You write a book about something, and people see everything in it.

Airbnb probably needs to stay sexy/cool for as long as they can before they become the big/unsexy/bureaucratic administrator/utility providor.
