I feel like this begins to blur the lines between discovery tool and resource to be discovered.

The idea of instructable /project blog is interesting as a discovery tool though. It makes me wonder if the act of creating one is also a discovery tool, similar to a lecture pad or research notebook. It's kind of like, active vs passive discovery, kind of like I wrote about in the other comment, where one might have to develop a certain "method" using various tools to create a reliable + repeatable process. Once I start searching for an answer or move towards a goal, by keeping a log of the steps, the "discovery" of something "novel" might be just where the knowledge gaps are - knowing what I don't know. But like asking questions of other people, this isn't automated, and requires skill/practice/time.
