Its great to see someone else is thinking about this. We actually started building a Badge repository service last year. - http://news.ycombinator.com/item?id=795952 http://news.ycombinator.com/item?id=795952 (KaBadge.com) We have since also built a rule engine to allow sites to create badges and award them based on specific combinations of events. (You won't find it on KaBadge, we have been playing a new domain, expect a post Monday asking for a review!) The biggest reason we created the rule engine was because people felt that the best area to create value. People commented about why would a site want to share their badges when they did all the hard to work figure out how to award them. I'm excited to see others noticing the growing trend and benefit of achievement engines. There are problems to solve, but the trick is finding the ones that will make money :)
