Announcements are sent to both the general mailing list and the announcements-only list, so in theory, you don't really need to subscribe to both lists but it has advantages.

(Meeting invites usually go to both this and Boston-PM-Announce list, but in case of last minute cancellation due to blizzard/hurricane/fire, i can only guarantee Announce and Twitter get the update. Also, Gmail can learn that things on Announce are Important, or rule/filter for Announce list for tagging/star. So I do recommend subscribing to both. -- Bill)
