Semantically related notes are conceptual gateways
In the case when two free learners create two different notes on the very same topic, a minuscule semantic distance might signal a conceptual gateway between them. Rather than being a case of two different notes building on each other, the two notes almost perfectly overlap. However, summarization forces understanding for both learners, which makes it almost advisable for a community to have multiple notes on the very same concept, written by different individuals. What’s more, conceptual gateways can also connect multiple notes of the same learner, which touch on similar ideas from various disciplinary angles, therefore breaking down conceptual silos.
