PostEaseAdd a take instead of dropping a bare link
Since a bare link post tends to underperform, the highest-value step in repurposing something for X is usually attaching a genuine, specific opinion about it, not editing the source material itself. What made the original interesting is exactly what gives people a reason to reply.
Break a long piece into a thread
An article or a long video with several distinct points can become a short thread, with each post covering one point in a self-contained way. A thread that can be understood a post at a time tends to hold up better than one that only makes sense read start to finish.
Cut video down, not just crop it
Since native video under a couple of minutes tends to perform best, a longer video usually needs a real cut down to its single strongest moment, not a straight re-upload of the full file. Pick the one clip that stands on its own without the surrounding context.
