I think that there could be a range of tools and options available at the discretion of each community.
Some communities may only be interested in an immutable forum. For others the opportunity to store assets / NFTs may be key with perhaps the potential to trade them against Hive or Bitcoin.
But I think that SMTs need to be an available option for each community if they want one. It just widens the potential for what you can do as a community if you have your own finance and rewards.
