This isn't a platform though, its just a way to relay your data, in theory your preffered hive front end could have a Nostr relay and broadcast your info to it or allow you to connect your relay to it, so you keep your content on there or a copy on your local and you can take it where you like and exclude it from sites you dont like
Funny you mention Minds, they are adding Nostr support soon, so well see how a bigger site handles the use of the tech going to be a great test for it
I personally don't see the point of crypto incentives paying you with inflation, because you just create a culture of token chasing and it kills the product, thats why this place is a ghost town, no one wants to have real discussion they're too focused on where can I secure my next token and it hollows out the product and as soon as that dries up people leave, which has been the case
