"Your Most Recent Bookmarks" vs "Most Recent Bookmarks from your Groups"

Is there some particular use for having your own bookmarks appear in the "Most Recent Bookmarks from your Groups" on a user's home page? If not I wonder if they should be eliminated from the list. It seems it just duplicates the "Your Most Recent Bookmarks" activity, for the most part, and potentially it could edge out activity from other users in your groups.
