One calendar, four algorithms. That’s the bug.

TL;DR

The calendar says, “Post this everywhere at 9am.” The feeds say, “Write it for us.”

YouTube is cutting reach for barely changed re-uploads, and Threads won’t give its Gems badge to posts republished from another app.

Before you post, ask yourself: “Could these two captions swap platforms without anyone noticing?”

Open a typical brand content calendar and you will find one row per day. One idea, one caption, one asset, and four little platform icons ticked beside it. It looks efficient. This month it started to look like a bug.

Four apps, four different questions#

In the space of two weeks, each of the big feeds has said out loud what it wants, and the answers do not match.

YouTube said on 1 October that Shorts recommendations will further favour original content and cut the reach of channels that mainly re-upload other people's clips. Its creator liaison, Rene Ritchie, was specific about what does not count as adding value: voice-over describing the screen, minor technical edits and "template-based bulk changes".

Threads launched Gems on 8 October, a badge for posts and replies that start real conversations. Originality is one of the tests, and the rules say plainly that posts republished from another app cannot qualify. Then on 13 October its head, Connor Hayes, said a recent change should show people more posts from accounts they follow, which for creators means "on average more reach to your followers".

LinkedIn spent September and October training its feed against what members report as low-effort, AI-sounding posts, with those reports now feeding the filter that checks anything shown beyond your own network.

Facebook this week began letting people tell its algorithm, in their own words, what they want to see more and less of, and why.

The common thread is not "post less"#

Read together, these changes reward the same thing from four angles. YouTube wants work that is yours. Threads wants something native to Threads, written for people who chose to follow you. LinkedIn wants a person, not a template. Facebook is handing viewers a remote control, which makes yesterday's engagement a weaker guarantee of tomorrow's reach.

What none of them rewards is the identical post pushed to four places at 9am. The scheduling is not the problem. The sameness is.

What it looks like in a feed#

Take a bakery announcing a new sourdough. The one-row version is a square photo, a caption with three hashtags and a link, posted everywhere.

The four-row version starts from the same idea. On Threads it is a question: what does everyone get wrong about sourdough? On LinkedIn it is the owner on why she stopped buying in flour, with the number of loaves she now sells before 10am. On Shorts it is the scoring of the loaf, filmed fresh, not the Reel downloaded with someone else's watermark. On Facebook it is the photo, the price and the opening hours, for the regulars who actually walk in.

Same idea, same week, same morning if you like. Four pieces of writing.

The calendar is still the right tool#

None of this is an argument against planning. Teams that plan once and write four times tend to ship more, not less, because the hard part, deciding what to say this week, happens once. The column that changes is the one beside the idea, which stops being a list of icons and becomes a list of drafts.

That is roughly how we think about Haba Social: one plan, with room for each network to get its own version. Whatever tool you use, the test is simple enough to apply to next Monday's slate. If you could swap the captions between two platforms and nobody would notice, one of them was not written for its audience.

The feeds are telling us what they want more openly than they have in years. It would be odd to keep answering all four with the same sentence.
