If this really bothers you, you might ask Ales Trtnik not to use the announcements tag on the weekly "News on the Database Errors Project." That's the only db_errors items that's tagged for announcements.Since there are now 419 people following db_errors versus just 176 following announcements, the change probably wouldn't substantially diminish the visibility of the weekly db_errors reports -- but before he does that he might want to alert people that they have to follow the db_errors tag to see that weekly report.
By the same token, I suppose some of the rest of us might appreciate it if people refrained from using the announcements tag to tell the rest of WikiTree about a new free-space page or a new one-name study, since these typically won't interest more than a small fraction of WikiTreers.
