Sam, I completely agree that things like photos and such should have a app filter on the profile. Mark mentioned a concern about this, fortunately I have an ace up my sleeve on how to address the issue. My vision of the profile apps is to have them be able to work as either a widget or an app depending on the admins choice. The big reason to have them display as apps is so that all the options are easily accessible to the user.
So in some respects Sam we are on the same page in terms of liking filters on the profile.
Eventually once EasySocial gets many of the other needed features I would love to see the article app have special abilities that allow the user to very easily find the content they want using article categories and a search method. Using ES's methods I know exactly how it would work.
