You're probably right about that.  I don't think making content about a post, even if it's a great one, would be interesting for long.  What I'd like to see is some interviews with the most well-known/most active members, though I don't necessarily mean something like an on-camera Q&A.  Anonymity is important, of course.  But that's the sort of thing that might be of interest to people to whom the forum is an important place--and there are more than enough members to focus on.

I'd also suggest keeping it a channel that's dedicated to forum issues, and not bitcoin-related ones.  There are tons of folks who are big fans of bitcointalk, so the bitcointalk forum shouldn't become another bitcoin channel.  That's probably not your intention, Cyrus, but I'm just thinking ahead.

And hey, I do remember when this was first suggested and I thought at that point someone would have done something to get the ball rolling.  Guess that didn't happen, but I'm stoked that it looks like a Youtube channel is going to become a reality!
