Unless it's 'zero becaue i don't have an account,' I disagree. I don't know until I land on a site whether they're using fb connect.

Block it, and use another browser for fb and fb only. For very-light users like me (as in, keep a nearly empty profile for the people that use it as default communication) it's not even inconvenient.

It's still within your control to block/not use FB connect even when you have an account.
