Generally I just go by a greedy algorithm of reading or listening to the currently most appealing thing, which keeps changing based on my mood and energy levels and what I find through reddit threads and other serendipitous discoveries. I did find a great new podcast recently: omega tau science & engineering podcast. I'm looking forward to listening to that in the new year. It's a long form (2 hours+) podcast taking a single sci tech area and interviewing an expert on it, without shying away from details. In books, I think I'll be reading more of the Very Short Introductions series from Oxford press, and also more of web fiction (including fan fiction). I was impressed by how effectively the VSI books (at least most of them) convey a large amount of understanding in that small space. I also discovered Mother of Learning (web fiction) and Brutal Harry/Harry Potter and the Natural 20 (fan fiction) in 2017, and realized there's a whole new form of fiction content that I'd been missing out on. I think (and hope) I'll be finding more of these this year.
