How are you keeping the community focused? And how are you dealing with armchair types? I don't expect you to ever get rid of them, and they can be useful, but is there a way to keep the real experts higher priority?
And then when you post, you select the topic/community and our algorithm does the targeting/distribution accordingly. This keeps your feed hyper-relevant as the network grows.
We've studied different network and community dynamics, and taken them into account when designing Shuffle as our aim is to become the hub for all of the fields out there.
