I see that you are writing on medium now, I didn't realize that. Glad to read your work again, I was sorry to see cultureramp.com go away. mk once asked one of the founders of reddit what the key to the success of the site was and the answer was subreddits. It gives the users ownership of a segment of the site. This ownership makes them "champions" of the site, effectively marketing their own subreddits outside of reddit itself, bringing in new people etc.

Created /r/bowling? Then you're going to get your bowling league to join reddit to participate etc. I've often wondered how Hubski could provide a way to give more "ownership" to the people in our community without having that "ownership" infringe on others experience as it seems the mod's have infringed (at times) on the experience of their fellow redditors. -As I've mentioned before, I'm not a redditor so I have no skin in the game but I do like to read these types of things to learn more about what does and what does not work.

Good seeing your work again, I look forward to more.
