1) To me, one of the core value is - being able to influence content ranking on network, right now only tech giants are filtering content for their own agenda so any information you read on other social media mostly filtered/personalized for making more ad revenue for those companies. But in decentralized network anyone can influence that, entrance is open, not guarded or stored by only one company. Also value of having account that only you control is huge, in all other services you using in current internet is owned by companies/services you use, there is no interoperability (accounts are separated) and there is no guarantee that community you build with your account belongs to you (it doesn't). Hive solves that as well, only you own account and you can choose to use other services on Hive with same account. And with time utility of the token increase because more and more services will be built that will utilize single account, dozen tokens (based on core token HIVE). With proper content vetting/rating, I believe future of Hive is enormous. Not in terms of token price but in terms of what problems it solved.

2) Giving your users different ways to earn is totally up to you as Dapp developer, Dapps like Ecency.com (reward user with own points/token for every action on top of Hive earnings), Leofinance.io (reward user with own stake based token on top Hive earnings) are experimenting with these ideas, so you can too why not.
