One of the ways to find new folks to follow on Cohost is to follow people whose posts you see shared by folks you do follow. But, I only have the brainpower to actually click through and follow people some of the time, and it's not necessarily when I'm looking at a cool new post.
It would be neat to be able to filter my home timeline down to just things from folks I don't follow which have been shared by the folks I do follow, so I can more easily find new folks to follow. If you follow my drift.
