Take a look at the Dragon forum on ChessPublishing.com: http://www.chesspublishing.com/yabb2/YaBB.pl?board=Dragons. You won't find annotated games there unless you join, but you will find some high-level discussion of the Dragon (along with the usual internet crap, of course). And if you're ready to buy a Dragon book, I would highly recommend Edward Dearing's Play the Sicilian Dragon.
