I notice I am sometimes posting general ‘community announcements’ - for instance the post about the final report of OpenRefine’s SDC grant, or the announcement of OpenRefine receiving the Wikimedia Coolest Tool Award. I’d love to see (and encourage) other OpenRefine users to do the same!
Besides the team announcements (which are the ‘official project announcements’ that people can subscribe to, as a newsletter-ish thing), how about also having a Community announcements category?
