Hi, I would be interested in hearing what it is that you learned from your friend. As mentioned in the [insert recent podcast].
If you were in need of an interviewer; I'd be happy to correspond but I'd be a terrible interviewer. I'm far too opinionated and a bit overbearing. I'm ok with that but I don't want to impose that on other people in the expectation of anything else.
This was written to you only, but then distributed to others who so found it appropriate to be listed among the set of people who read this or otherwise encountered it's information and decided that it was written to them, but it's actually you.
What is the size of that set? Is that a function of space? Time? My social networks?
