It might potentially be very interesting to know who is participating in the sense of just receiving emails by subscribing to the list without sending any messages. But that data is typically not public; probably mostly for spam-protection reasons, but there might also be a privacy interest in subscribing to a mailing list without letting others know that you have.</div><div><br class=""></div><div>People who operate mailing lists do have access to that subscriber list, so you could potentially get mailing list owners to share that data for research purposes under some sort of confidentiality agreement and with IRB review. I haven't gotten to that point yet, but it could be useful for comparing those who lurk on governance/decision-making mailing lists to those who send messages.</div><br class=""><div class="">—npd</div></body></html>
