Has thought been given to allow BadgeOS achievements to get their own activity stream type? This would allow it to be filterable and not be confused with normal 'status updates' (which they currently are).
Our purpose: we display people's status updates in a widget, however that widget is now displaying their earned badges. These are distinct actions from each other, and should not be confused. If BadgeOS made their activity a separate 'type', this would get cleared up.
