I tried blinkist but it never stuck. I think long-form stuff is better for developing semantic memory. Sure you can get to the point quicker with shorter form content, but tends to be less sticky.
I haven't gone back to blinkist to try this but I think a way to build up semantic memory with blinkist would be listening to every single title in a specific category to go really deep on that one category. At that point you're doing the equivalent of reading a full length non-fiction book anyway, so you haven't saved time, but at least you could triangulate what the core ideas / themes are through the entire category and really get the lay of the land whilst also getting the core messages deeply ingrained.
