I'm not sure exactly what they have up their sleeves, but a part of their plan is their 'Hunt tokens for Social Media shares'... you basically get 9 HUNT tokens for each outside view you bring to the platform. I've given away pretty much my entire non-Steem social media presence, but it did make me consider starting something up to get a lot of sharing happening... some Steemians do still have big Twitter follower numbers though, so if they are interested in hunts, they may bring some new people to the platform. Steemhunt is basically in it's advertising phase at the moment.
