Yeah, I picked up a bunch. As a programmer I had some thoughs on RDD about how they could integrate it into a PHPBB/etc sort of plugin framework. Thousands of those forum sites out there using some sort of Kudos system... adding actual monetary value to it would be a win for the forum owners, the visitors, and for the RDD team.
Sure, not as "high profile" as FB/Twitter/etc... but 5000 small fish can outweigh one whale, and create real momentum to make those big companies look a bit closer.
