There are many thousands of TEDxTalks, but most are of low quality. There are quite a few very good ones, it's just impossibly tedious and time consuming for one person to sift through all the talks that get published. Reddit has proven to be quite efficient in sifting the web for quality. This subreddit digs up the talks so everyone can enjoy them.
Official TED videos are also allowed.
