I'm increasingly becoming a fan of homemade youtube channels in general. Stuffandthings is my favorite pipe related channel. I also, like Classical Pipes and J Piper reviews. Posthuman Piper has a really good / informative series on cellaring tobacco, but most of his videos are just responses to other videos which I have zero interest in.

A few other channels I've liked but don't subscribe to are:
StogieFarts
DanTheSmokingMan
Cutlery Lover
