S3 added a reference and explained that they "Don't want to plagiarize". They also changed the textual content to the reference.

The ability to improve nodes over time improved the quality of the nodes greatly. This allowed users to fix duplicate nodes, add references where needed, improve definitions and explanations, add diagrams or deleted unnecessary ones, and more.

Do we see any benefits in the evolution of these nodes (related to the path diagram technology study) over time, or the very first proposal for each of them was helpful enough and the evolution did not help that much? (5)
