I am a massive fan of YouTube. I must spend over 3 hours a weeks watching swings and videos from various other coaches to get fresh ideas and just to listen to people with a different point of view from myself. As a coach, I like to keep my views rounded so for me its the perfect platform to see and hear what other people have to say. I use it also to study pros golf swings as you can normally find a decent slow motion version of most players golf swings. So for for me its a great resource and the world a better place for it!
However, YouTube also keeps me busy as I regularly have to sort out players completely messed up from watching too many videos. Conflicting ideas, drills that promised the world, imitating a players golf swing, I have seen it all and have to deal with these kind of issues. The trouble with amateurs players watching videos is you get drawn into believing what the coach or pro is saying is relevant to your own game where in fact what he is saying couldn't be further from what you should actually be working on. As a coach, I try and stay away from doing generic quick tip videos for this very reason because you can end up doing more harm than good.
Thats why using YouTube as an alternative to seeking the advice of a coach simply does not work because firstly the information may not be relevant and secondly the execution of a drill or move you may have seen could be completely out anyway. So my advice is use it with caution but if you work with a pro, always seek their approval before going off on an experimental tangent. Its easy to share links so do that before meddling!
