If you find several worthwhile articles in a day, you need not publish them all immediately. The original post described Buffer as a queue for tweets. The idea was simple: distribute messages across the week instead of filling followers’ timelines at once.
Schedule with care
Buffer still supports scheduling posts for X. Its name, features and terms have changed since the old Bufferapp article. Use current documentation for the controls rather than instructions or screenshots from 2011.
Planning begins with the content. Ask why someone would click or respond to each post. Add a short comment of your own to a shared article, check the link and make sure the words will still make sense when the post goes out. A message about an event can be outdated if it appears days later.
Leave room for conversation
A queue may create a regular presence, but it does not hold a conversation by itself. Check for questions and replies after publication and respond when appropriate. Do not repeat the same message automatically just to fill empty slots. X has rules for automated and repetitive posts.
My old assumption that spacing posts would automatically prevent unfollows was speculative. Look instead at the quality of your posts and your audience’s response. If a schedule helps you publish more calmly and accurately, Buffer has served its purpose. If it only produces more posts, scheduling less may be better.
