Somebody says repurpose, and a good long piece becomes ten short posts that each say a tenth of something. The original loses its argument and the ten pieces have none.
The same argument told to a different audience in a different place is repurposing. Chopping one argument into ten fragments is dilution, and every fragment is weaker than the whole because the reasoning was the value.
A figure you produced and a concrete story survive any format. The transitions, the caveats and the structure do not, and trying to carry them is what makes short versions read like offcuts.
