When I wrote about ManageFlitter in 2011, my Twitter feed was becoming difficult to follow. The tool showed accounts that had been inactive for a long time and people who did not follow you back. You could then decide for yourself whom to unfollow. It was mainly a way to reduce the volume of posts.
ManageFlitter officially says its service has been unavailable since January 2022. Its old buttons and filters are no longer instructions. The underlying question still matters: which accounts bring you value, and which do you follow out of habit?
Make your feed useful
Occasionally review the accounts you follow. Do you enjoy their posts? Do they help you learn, keep up with a person or understand relevant developments? If their content no longer interests you, you can unfollow or mute them. Muting can help when you want to preserve a connection without seeing every post in your feed.
An account that rarely posts is not necessarily useless. Someone may share little but offer valuable information at important moments. Equally, a lack of a reciprocal follow is not by itself a reason to remove someone. The old emphasis on who follows you back does not fit every purpose for using a network.
Avoid automatic cleanups
An outside tool that asks for account access may receive broad permissions. Check its provider, requested rights and the platform's current rules before connecting it. Unfollowing people in bulk based on one filter can also discard valuable relationships.
The enduring part of my original tip is not ManageFlitter itself. It is the deliberate shaping of your information environment. A smaller, better chosen feed may make it easier to focus on what you actually want to read.
