For what it's worth what sold me on .world is the slogan, front-page of the internet. It may or may not be misleading but I'm after a Reddit replacement with a mix of all communities.
As I explore more I may go elsewhere but so far it has the Reddit feel.
That was the thing with Reddit, go with the hive mind or be downvoted into oblivion. It will be the same here eventually, human nature won't change with a new platform.
