As I go through the process of re-tagging my blogs that don't have a primary tag, they are all appearing in my activity stream, and presumably in the stream of everyone following me. I guess that's a good thing from the point of view of getting eyes on my old content, but when everyone goes through this process it is going to make the activity stream very noisy, and probably close to useless for a while. Is there a way to stop these minor changes appearing the the activity stream? There used to be a "this is a minor update" checkbox in the old SCN that did this, didn't there? Is there an equivalent now?
