This is something that was started on another forum I frequent, and I thought it was a good idea. Youtube can be such a huge resource that gathering all the cool videos into one place can't possibly be a bad idea (I know, I know, famous last words).
Try to keep the chatter down, or if you are going to chatter, then post a cool video with every post. If this works, then we could have something really cool.
ETA: Videos, unless there is objection, can be anything forging, grinding, knifemaking tool related. However, try not to stray too far away. Eg. "450 lb powerhammer"- Awesome. "Fitting guards"- cool. "epic knife fail LOL XD"- not so much
