I honestly do not mind it one but. I quite like the interface. It’s minimal but there are some bugs to it which is to be expected. I really do like the overall design of it though. There isn’t too much going on. It’s like old Reddit which I am a big fan of
But that’s the whole point: the is no centralised organisation. Which is the reason most of us are here. Duplication is just an unavoidable side-effect.
And it’s not as if reddit were immune from that. Lots of similarly named subreddits on the same topic.
So that’s not something that is “to be done”. (Unless you meant TBH: to be honest.)
