Agreed. I was just curious about why, specifically, the parent poster never schedules follow-ups. If the discussion in question was actually valuable, it seems like they would want to pick it up later (or use your approach of just forking off immediately. I look at those two things are being approximately equivalent).

That can be hard -- many / some people would be worried it'd be impolite to leave and in a way say "the things you're talking about aren't interesting to me".

And they'll stay and feel frustrated, in silence.
