back on Birdchan, I used to make the case that every account should have at least 2 feeds: the main feed, and then a secondary feed for things like live-tweeting sporting events, competitions, etc.
For those that want to follow, go to the second feed of person, but not impact the main timelines, etc.
With some of the other #Fediverse projects like Hubzilla, Calckey, etc. already having some version of channels or secondary feeds, I'd still love to see that model in some form.
