Do you mean like the "Social Groups are Live", etc? Things post things posted there by the bump? That's an individual setting and you just hover over the star in the middle for bookmarking and a gear icon will appear, just click that and click dismiss. It gets rid of the junk stuff at the top so only our discussions show. You just have to do each one individually.
