In a word: Curation
The amount of great information ML has amassed has long outgrown the format where you search for a specific topic and then watch a single stream (or listen to a specific podcast). The topics and discussions covered within each piece of content are so broad that users can’t find information quickly (nor can we find all the relevant information). And the information is only useful if we can find it quickly and efficiently.
Each podcast, each stream, once created, should have someone go through and create an index so when you search, you are able to find cues/links that take you to that part of the stream/podcast. In addition (for starters) I would suggest that all of the streams (and cues) are clearly labelled for the date of original broadcast to help contextualize the information.
I noticed that @Bonsai_Bentley posted a comment about the soil science stream pointing out another need for curation. Sometimes information is posted that turns out to be just plain wrong or misleading. This should either be culled in retrospect or be labelled with an advisory which points to more recent updates. The Soil “Science” podcast (and accompanying stream) is case in point. I stopped listening part way through the first one because it seemed like what Ian was espousing was more like a religion than a science. I come from a background in micro- and molecular biology, I was so pumped to hear what he had to say. But my BS meter was off the charts pretty quickly, I just couldn’t continue. And I hasten to add that I love the Asymmetry podcast, I had never turned one off partway through before. I only came back to the third episode when I noticed the description mentioned that things did not turn out well (and even that one was painful to listen through). I wanted to find out what happened.
As @Bonsai_Bentley also points out, Ryan has commented on the record many times that he does not want to write a book because he does not want people pointing out errors in retrospect. But ML has the potential to be so much more than an encyclopedic bonsai book, it can be the most modern up to date reference manual. But that is only as good as the indexing/curation. I recognize that requires investment, but I assure you it is one well worth making.
