People would often benefit from more "line management", and could often get it just by setting up weekly meetings with someone else who's in a similar boat

A chunk of the interview is devoted to these points. From memory, some points made were:

• It can be weirdly useful to have ~weekly meetings to just discuss what one did last week, what went well and poorly, what one's goals are, and what one plans to do next week
  • The reason the usefulness is weird/surprising is that a lot of the benefit seems to come from just having these meetings at all and being asked obvious questions like "Would that task really be the best thing to do to achieve your goals?"
    • And in theory, one could just simulate these conversations by oneself
    • But at least for many people, it seems to be more effective to have an actual conversation with another person
  • This can help with both productivity (including getting the right tasks done) and mood (e.g., reducing self-doubt or a sense of listlessness)
• Some people don't have someone to provide that "line management" role
  • E.g., people in PhD programs might not get frequent enough meetings with their advisor, or it might be clear that their advisor doesn't care about or is terrible at management
• Those people might benefit from just arranging to have weekly meetings with a friend, colleague, fellow student, or similar who's in a similar boat
  • Having weekly meetings with the same person allows them to have more context on one's full situation, goals, skills, etc., which seems helpful for this
  • PhD students could arrange this themselves, and it might help combat PhD programs often seeming to be unusually crushing experiences (due to a lack of guidance, feedback, etc.)
  • (Something I'm not sure they explicitly said, but which seems true: This could probably be useful even for people who do have meetings with a line manager, if the person would benefit from meeting more, or if the manager sucks.)

That first point resonated with me very much. I received basically no line management at the school I taught at, and that sucked, and I only realised how much it sucked once I moved into roles where I did have weekly line management style meetings and discovered how helpful they were (both for my productivity and for my mood). 

And that third point seemed like an obvious but great idea. I intend to apply it myself if I find myself in a future situation where it's relevant. And I intend to keep it in mind as something to maybe suggest to people, when it seems relevant. 

Some reasons why Rob thinks long (e.g., 2-6 hour) interviews are an unusually good medium for sharing ideas

(This is from memory and there's no transcript, so I'm probably missing some things and distorting other things. Also, I think Rob has written about this elsewhere, but I can't remember where.)

• It's usually easier to pay attention to a spoken discussion than to something written (even if it's later read aloud, as in audiobook)
  • The social aspect of discussions keep them engaging
• Interviewees will essentially always have to cover the basics of an idea if they want to talk about it. If they have enough time, they'll also cover key counterpoints. But usually they don't have enough time to go beyond that and discuss the counterpoints to those, and to those, and so on. 
  • So three 1-hour interviews will probably cover similar ground each time, and never get to a lot of what the interviewee finds most interesting about the idea. 
  • In contrast, one 3 hour interview can cover the basic stuff just once, and then spend the rest of the time on interesting further points.
• It takes much longer to write ideas up well than to say them in conversation
  • Expressing ideas through speech comes more naturally to people
  • Speech allows for conveying things like uncertainty through tone, pauses, etc.
• (Related to the above) Usually, there are a bunch of ideas that are well-known among specialists in a given field, but which haven't yet been written up and which are thus known to very few people outside of that field. Historically, the main way to learn these ideas has been to have 1-1 discussions with a specialist. Obviously, most people don't get a chance to do this. But now a specialist can have such a 1-1 discussion and then huge numbers of other people can listen to that.
  • So that means more people can get a sense of the latest thinking in a field than was previously possible

I agree with all of these points. 

And I found the final point particularly interesting. In my limited experience as a researcher so far, I have indeed been struck by how many interesting and potentially important ideas, framings, elaborations, counterpoints, etc. seem to be floating around in discussions, work-in-progress talks, internal drafts, etc., but haven't been fleshed out fully in any widely accessible content. Often there'll be some mention of these things in widely accessible content, but missing lots of details, or framed in a way the researchers not feel isn't quite right. And I think unfortunately this is a totally understandable and hard-to-fix problem, and applies to some of my own work and ideas as well.

I think more long interviews with specialists in various areas - not just researchers but also practitioners, grantmakers, etc. - seems like a great, low-cost way to address that issue. And I'm glad various people are already creating such interviews.

Currently, I think it'd be a good idea for all future episodes that appear in the 80k podcast feed to be linkposted to the Forum

I'm currently in discussion with 80K about how and whether they want to crosspost their podcast episodes. I'd prefer to crosspost the full text, so that terms from the episodes show up when you use the Forum's search function. But summaries might be more likely to invite comments? I'm unsure.

As a data point, I found this super useful and would love to see these happen for each episode. Two particular ways I'd benefit: (i) typically there are a few particularly interesting bits in each episode which I found particularly novel/helpful and reading over a post later which re-states those will help them sink in more, (ii) sometimes I skip an episode based on the title but would read over something like this to glean any quick useful things and then maybe listen to the whole thing if it looked particularly useful.

I haven't ever (and doubt I will) read over a full transcript, so posting those wouldn't do the same thing. Also, putting the particularly interesting insights as comments allows upvoting to triage the insights that are most useful for the community.
