I think questions about specific web sites don't belong on Super User.
As the faq states:
Super User is for computer enthusiasts and power users. If you have a question about ...
- computer hardware
- computer software
… and it is not about videogames or consoles, then you're in the right place to ask your question!
The specific question you mention (https://superuser.com/questions/73214/facebook-profiles-for-non-people-okay) is definitely a no go and I voted to close it.
This one (https://superuser.com/questions/61974/find-out-when-someone-defriends-me) I also voted to close.
This one (https://superuser.com/questions/4366/facebook-upload-problem-with-the-java-photo-uploader) is ok as it appears to be a problem with the OP's browser's cookies. A computer software problem, so fine with the faq.
