When you hear about semantic diversity, do you ever think about EdSense, Moodle, EdX, Coursera, etc., as examples of semantic diversity?
And semantic silos?
All content delivery systems are semantic silos.
They have made choices about storage, access and delivery that had semantics. In addition to the semantics of your content.
The question is whether your silo will become a sepulcher for your content or bricks for the next silo in turn.
