@johnjohnston as one of the originals John, i am sure that you have seen some changes in the last 10+
@mrkrndvs yes, been fascinating. There is a tension with those that want to keep TeachMeets going along the original principles, no keynoters, no privilege and the attractiveness of TM as a space to sell or recruit( to products and ideas). Personally think there are enough spaces that TeachMeet would ideally stick to principles.
@johnjohnston here in Aus, I have found that different contexts produce different results. Sydney is still relatively active, while the community in Melbourne has waned.
@mrkrndvs ironically in Scotland there are only a few a year but pedagoo serves a similar, but perhaps better organised, function.
