It's possible another fediverse tool would match more what you are aiming for, kbin might not be too far off but it and lemmy definitely seem more about focusing on communities / discussions than people. Definitely check out mastodon / firefish / akkoma
Edit: I do want to say I think kbin could be good for that in the future; RheingoldRiver and others have put in a bunch of good issues about improving how microblogs are displayed / discovered, but I find it still a bit rough to notice microblog posters at the moment
