To me, it seems like this question should more often be posed in its inverse. Most people don't have a problem with using Facebook for everything. In my experience, at least, it's engineers who are most likely to have a problem with using Facebook for any given task.

That's also my experience. Also, the older the person the less likely they are to want to connect with Facebook.

But non-technical people under 30? No problemo.
