Smoking the bacn - Similar to my “no press releases” trick, filter any email that contains the string “to unsubscribe.” Although many of these certainly will be valuable (sign-ups, Google lists), that string means there’s a good chance they’re also bulk messages that are being generated automatically. And some folks want to only see those sorts of emails, again, once or twice a day — and only when they have extra time (read as: don’t interrupt me whenever someone on Facebook wants me to be a zombie, or whatever).
Remove the comfort - Related to the “no gadgets” rule, some groups are reportedly trying to reduce meeting time by making it less fun and comfortable to sit around for an hour or two. This can range from no longer “catering” meetings with food and water, to shutting off wi-fi, to more extreme measures, such as no-chair meetings.
