YouTube is the new Google.
However the old statement "Buyer Beware" comes screaming into my head at the same time. It can be a time suck as well so I have found one way around it quite similar sounding to yours.
I listen to financial pundits on YouTube, but not on the computer... I copy the links, email them to myself and listen to them driving or doing mundane non thought tasks.
I also use it to watch what my competition is doing and to feed my facebook folks. It is the Yin and Yang of the Internet in my opinion, but has great value when used accordingly.
Interesting insight @jameshowarrd.
Indeed it has great vaule and I'm not one that usually wastes any time on it. My wife uses it a lot for how to videos when she need to learn a knew crochet stich but it's very rare that you'll find me on it unless I have some cleaning to do :-)
I like the idea of saving the link like that good tip for anyone.
