The buzz at Fortune Brainstorm Tech last weekend, as I mentioned in Monday’s Postcard, was much about the power of online games. Google , Walt Disney , and lots of startup folks view social games as a most efficient pathway to getting active Internet users to spend money online.

(Thanks, JP, even though at Brainstorm Tech I hung out with Zynga CEO Mark Pincus, the king of online games, I’m not a gamer gal.) “How social gaming became the future of the Internet” explains the trend.
