I think it depends a lot, some follow lists will have huge overlaps with your kind:3, some will have no overlap.

It would suck for me to have to re-follow all the people I’m interested in reading long-forms because that’s pretty much exactly my kind:3.

To be clear; it’s a different event, what I’m talking about is the tooling to make this empowering instead of detrimental to people using this. 

 Sure. I think we made a mistake when we change the kind3 list from contact list to follow list. We could keep all contacts there and then have different follows per kind as 30000 lists.
