Haven't watched yet, but I really like this guy. I watched his how-to video on soldering before I re-did the crossovers in my Maggies. He is an asset to the audiophile community.
Think about this though, on top of your day job, and moderating your own sub-forum, you start a You Tube channel. You want plenty of hits, and you have initial intentions to provide great communication to watchers, and respond to every comment. And then you get successful, and it provides you with some income, wonderful! And then you get really successful- After 1 day he already has 575 comments! How would any sane person find the time to read and respond to them all.
