I think listening to audio is more conducive to "drive by learning". It allows your eyes to get distracted and you can maintain some level of attention for a longer period. Our brains are also simply better at picking clues signalling the important stuff, when listening to someone speaking.
I have turned HN into a personal data-oriented wikipedia and I want to test consuming the resulting feed through audio (like a npr for data-based facts) [0].
If some of you would like to take part into the experiment, leave a comment below !
