Yeah, this seems like it might be useful for people who follow loads of accounts. I follow about 40, and I want to read literally everything all of them say. So long as it doesn't fuck up that use-case (e.g. by remaining optional), I'm fine with it.
Twitter would be really really cool if you could have your lists and then swipe through them like you do with the "Moments" feature (which is awful)
I actually use Facebook the same way too.
Yeah, I'd probably like this. I follow a LOT of people (right at the limit of how many you can follow) and I never expect to read every tweet. I just expect to check Twitter every now and then, and find a few useful / interesting nuggets of news. And occasionally I do a #hashtag search if I want to catch up on a specific topic.
So, for me, this kind of feature makes a lot of sense, as long as the algorithm does a good job of picking out the "good stuff".
It may not be for everybody, but I can see this being valuable for at least some percentage of Twitter users.
