I must have made it to a fresh circle of academic hell because this week after the talk I got my first “it’s not a question, more of a comment” EMAIL.
@solderandchaos A few times I’ve been to talks recently, at the start of the Q&A when the moderator has asked for questions, they’ve followed up with “and, although a long rambling statement followed by “what do you think about that?” is technically a question, it isn’t a very good one.”
Not sure how that might be adapted to stave off follow-up emails though, sorry!
