> I carefully curate the people I follow, roughly for any given day, I can read the tweets in my timeline written on that day - all of them. When twitter's algorithm "surfaces" certain tweets, it removes them from the regular timeline, so if I dismiss their seemingly randomly selected "While you were away", I wont ever see them again! How brain-damaged is this?

I have the exact same issue; I follow less than thirty accounts, and I want to read everything from all of them. When I tried dismissing the "While you were away...", I was missing many tweets, so I was forced to turn it back on.
