Youtube has been a great learning tool for me. I repaired appliances, rebuilt a transmission on my 4x4 Jeep, all sorts of things I'd never tackle on my own.
So true, isn't it? I can't tell you how many times I dropped tools and walked into the house thinking "This probably isn't on YouTube..." and it was.

I had a laptop in the shop and just kept advancing and pausing the video until I got it all done. No way in hell I ever would have figured that out on my own.
And on the same learning topic, I find myself (sometimes hours) reading and exploring things that while working would never have had the time for. Someone will mention something about a historical event, or technology, or an old car (hobby of mine) and Google and read, and watch videos for house. Yesterday Googled the Porsche 356SL and ended up watching a 30 minute video of Jay Leno's garage where they featured "#46" a 1951 SL that was Porsche's first entry into Le Mans....
