I keep pretty good tabs on most HN'ers that are more than just 'talk', and there are a couple that stand out, you guys couldn't hide it if you wanted to :)

There are others too though, maybe I should do a bit of a write-up on the 'hidden gems', it's very easy to lose track of who does what with the number of announcements here. Some people really deserve a bit more of the spotlight because of their achievements.
