I have only recently been diagnosed and I do watch You Tube videos on Autism as a way of educating myself about autism. It's a subject I know very little about as I've only just started researching it a few months ago. The Youtube channels I find helpful are "That Autistic Guy" and "Aspergers From The Inside". TED talks also have a few helpful videos on the subject. Always be careful with Youtube as you can't believe everything on the internet! LOL!
The Youtube videos were helpful in the beginning but after a while, they all seem to sound the same. The information doesn't really change that much. It's worth a look though!
