Perhaps with time, and maybe more users, people can start to organize into sub-networks with shared interests, by followers or hashtags.
Perhaps hashtags could serve as a function for topic based thread organization.
Does it need a clear focus? If, like you say, there are subreddits for everything you need, maybe it works to have subreply as a group chat, exposing us to things we might not normally talk about? :)
It's more of a twitter replacement than reddit. We're just using it as reddit through trending and search because it's really small. If it ever blows up then your feed is where you're going to spend your time.
I like that you can start a conversation about anything, and it doesn't depend on finding an article on that topic first.
As long as we can stamp out right wing / racist / white opinions entirely, then I think this platform could be a contender... otherwise it will be relegated to the dustbin as with any other sad whiteboi nationalism project
If you are looking for a new reddit replacement checkout dev.lemmy.ml. Federated reddit is the future.
I think this format organized around subtopics Could be really popular
