Actually, I would argue that we are seeing the success of crypto social sites that do reward evenly by giving all participants equal voting authority. Minds.com and LBRY are drawing in the big names from Youtube, Twitter and the other places while Steem gets a link posted at best. Stake-based social medias might just not work, or perhaps most people just don't like the unfairness of the influence it gives the minority over the majority. Either way, I'd say Minds.com and LBRY, though young projects, are kicking Steem's ass.
