So when I see a Like button on a site I've never visited before, that displays my name, FB avatar + social data - you're saying that the site I'm on has no way to know that I've visited it unless I click the Like button? Only Facebook knows that and is displaying it in a way that is undetectable to the owner of the site?
This is a bit over my head programmatically but that doesn't seem possible. If Facebook is serving something to visitors on my site, surely there must be a way for me to capture that data?
