Facebook being a little bit more open would go a long way, RWX like a good old FTP-server. I'm not active on Facebook and I can't even read the posts of my wife without becoming a member or signing in. A read-only mode would allow me at least to read her posts - or other. I completely understand that Facebook requires you to become a member to post messages and upload stuff on its platform (write), let alone execute things, but now it's way too closed.
