There's a website with educational videos about linguistics called the Ling Space. There's also twitter, tumblr, discussion boards, google+ and of course also a page in the book of faces.
I really like the one on allophones.
Id you're a person interested in linguistics and curious about it all, you should really go watch this. There's lots of similar initiatives like this, but this one is really good in that it's good bite sized bits of information and clearly presented. I've often thought of doing something very, very similar in future, but just not had the time, resources, energy etc. I'm very glad this exists.
This is a great thing, go go.
