You Tube is like Television: Mind-numbing 99% of the time. If it went away tomorrow, I would be completely oblivious except for one fact; My wife and daughter are from Russia. They listen to music, watch ballet, see what is happening in their home town, listen to people speaking their native language. Having spent some time overseas myself, I can at least imagine the comfort they get from having access to this bit of home. I recall times when I would have given a weeks pay to just sit and listen to some music in my own language while I was in Korea eating too much kimchea and drinking too much soju.
I can't stand stuff like You Tube, but I sure do see the positive side of it for a couple of people I care about! :-)
Guess it all depends on your point of view...
...the majority is always wrong, and always the last to know about it...
