It is fine to enjoy a feature and to want it improved. Just don’t claim that missing this feature destroys knowledge management.
In my opinion, quotes’ text should be left untouched, thus explicitly tagged with keywords of choice. For example, could tag with the single keyword #car all of the following quotes:
- "They go there by car."
- "They used their automobiles."
- "They drοve there."
- "They rolled there."
Accordingly, the graph will have only a page car, not having pages for automobile, drove, rolled etc. Please realize that, even if you tried the unlinked references in page drive or roll, you wouldn’t find the words drove and rolled. In other words, you don’t link words, you link concepts. Concepts come in so many forms, that no scanning can find them all for you.
