Yeah, it's definitely street cred.  They might also be getting their
students to sign waivers of some sort.  I don't know.

But the bottom line is that doing *quality* video is darn expensive.
It may even require multiple takes with a willing audience.  That's
not cheap.  And putting out poor video is not, I think, consistent
with our general preference.
