yes, you have to do it
This was really helpful! The section on extremely hands-off managers helped me to understand mine in a way that I hadn't been able to put words on before.
I think a talk version could be useful. The main pitfall I see being that talks are typically for a more general audience than newsletter subscribers, and a talk on a subject like manager relationships could run the risk of becoming generic (which the blog post absolutely was not). This specific categorization of manager types was new to me, though, so I think leaning on that could work well.
