Threads should split, never truncate

Every publishing tool eventually meets the same bug: a post that is longer than the platform allows. The lazy fix is truncation, and it is worse than a crash, because it publishes. A seven-part idea goes out as one tweet that ends mid-sentence, and nobody notices until a reader does.

Splitting is the honest fix

When copy runs past a platform limit, Postrim splits it into a numbered thread where every part fits. Sentences stay whole, the numbering tells readers there is more, and the full idea ships instead of the first 280 characters of it.

Platforms without threads

X, Threads and Bluesky chain replies. LinkedIn and the rest do not, so on those platforms the parts fold back into one post rather than dropping the tail. The rule underneath is simple: never publish less than what you wrote.

Media follows its part

In a thread, each image belongs to a specific part, not to the thread as a whole. Screenshots stay with the paragraph that references them instead of piling onto the opening post while the replies go out bare.
