I think all of the above use cases (censorship-resistant content blockchain, ad platform, DApps, content discovery/incentivization) make sense and also can work together. The most valuable thing of Hive is its community (users, devs and investors). Everything should be built around that asset. Also noteworthy to add is that Hive with its BitShares roots, has always been a DeFi platform also and even enables to lend and borrow Hive with its delegation system from the very beginning. Hive implemented a social-contract based stablecoin and a DEX (internal market) and also has some interesting new DeFi apps such as hive-engine or the NFT showroom. I think we should also list and promote our DeFi apps on hivedapps.com.
