I don't use Kbin, so this is a fediverse thing in general. But the biggest thing I struggle with is multiple communities getting added in different places for the same thing. Most people don't want to check Ask Lemmy, Ask Kbin, and Ask a dozen different spots. They just want it all in one consolidated place like Ask Reddit.

I feel like an app could help solve that by aggregating the communities into one view. But even then, you'd likely get a lot of reposts stemming from the individual communities. Not sure if there could ever be a solution for this, since it's the biggest selling point of the fediverse.
