I'm going to keep banging the drum here that the fact Kbin.social exists and is basically the instance is why it's gaining traction over Lemmy, which is far more splintered.
Not having to choose an instance massively reduces the barrier to entry for newbies. I really don't think we should be pushing people to other instances if we can help it right now, that can be a consideration further down the line.
