Better than removing the deluge of unwanted app notifications individually would be a list, off to the side, of apps your friends have used that you haven't opted in or out of yet. Opt in and they all show up, opt out and it's added to a list of unwanted apps in your profile that you can edit later if desired. Obviously this would make users happy but not app makers, because the way it currently works is free (obnoxious) advertising for them. The mixed-access to updates based on bi- or unidirectional association is one of the very nice things about LiveJournal's social scheme. I knew a few people who use FaceBook for one level of communication and retain their LiveJournal accounts for another, because of this.
