Corrections posted to social media never have quite the same reach as the original.
A correction isn't likely to be shocking, or salacious. Who cares if "He *didn't* have an affair" or "common trusted thing *isn't* secretly plotting to kill you." ?
What if on the fedi we can be different? Make "correction boost" part of the culture here?
A tag the original post. Make a new post with the correction. And we make an effort to make corrections go big?
