Tim Hardwick, writing for MacRumors:
In a change that is sure to draw the ire of some users, Twitter has removed the sparkle-shaped icon from the top-right of the app’s interface that let users switch between “For You” and “Latest” and replaced it with two tabs called “For You” and “Following.”
“For You” still shows users tweets from people they follow out of order, sprinkled with algorithmically suggested tweets from people they don’t, while “Following” shows tweets in pure reverse chronological order.
While the change technically makes it easier to switch timelines – users can now just swipe between them instead of tapping the star icon – users on iOS will now always see the algorithmic “For You” tab when opening the app, whether they want to or not.
I completely understand why Twitter wants you to use the algorithmic feed, but they should always give you an option to show a reverse chronological feed by default.
