In my mind Flickr provides probably the best page-flow pattern. So I’m saying the PROVIDERS are making this anti-pattern possible. Facebook must make it VERY easy to export users, so must Gmail and so must Yahoo etc. This must be standardized so that containers (using Open Social terminology) can provide that data using some kind of token system, and it must also happen in a process that doesn’t ask for you user/pass. I believe that because it’s not possible, networks are leaving developers with no other option but to do screen scraping.
