It has been interesting to observe the steady collapse of both my home and local feed here as people I follow churn out / go inactive.

It is a basics logistics problem that happens in all social systems. You get a group together. People leave the group. There's no low cost / low energy method of topping off the group. Social density drops below stall limit.

I _could_ add a bunch of people to my follower list but that's a high cost action. Tapped my friend lists. Other feeds are high noise.
