I nominate @spl and their post explaining what they do in the steemit poker community. https://steemit.com/poker/@spl/lucksacks-poker-spl-who-we-are-what-we-do-and-how-you-can-join-us
This is one of the most ingenious and generous uses of steem in the community: a couple of steemians built an online, browser-based poker portal. It's free to sign-up and free to play and they've given out over 4,000 SBD in prizes to date. @spl used to host 200 SBD tournies based entirely on post payouts, but, despite the obvious demand from the community for free-to-play poker with real SBD prizes, post payouts have diminished to bare-bones levels. @spl deserves a @bellyrub because the post will directly fund free, fun poker games on Lucksacks.
