I tend to agree with David on S/N ratio of this yutube stuff. There's plenty of smart clever people putting stuff up, but the yutubes seem to be way too long - probably to keep viewers on-site to maximize ad revenue. Most stuff I've seen takes maybe ten minutes to a half hour to describe or explain something that could be written on a single page .pdf - maybe two pages if there are pictures or diagrams needed.
There are some good to great ones, where you really do want to see video of things being opened up for discovery of what's inside and such, but even then, the run time seems way longer than necessary to get the picture, so to speak.
