By that I mean that cohost should support a mode that only displays the latest post from each user you follow and they're still in reverse chronological order. So, for example, if you follow N people then your timeline always has exactly N posts (1 post from each person you follow).
In other words, if someone you follow creates a new post then their old post is deleted from your timeline and their new post is added to the top of your timeline. If you want to see older posts from any users you follow you click through to their profile page.
The motivation behind this is to make your timeline less sensitive to post hogs who drown out other posts because they post a lot.
Hell, cohost could even guard this feature behind a subscription (people would pay for this feature!)
"fraidycat mode" is named after the fraidycat browser extension / app, which works like this. h/t to @exodrifter for introducing me to this neat idea.
