> I'd really like to know everything FB tracks on those like buttons, it's probably an obscene amount of personal data.
When you request a page like this guardian article, all they'd have access to would be:
* The url you requested, along with time and IP
* Any facebook.com/facebook.net cookies you have stored
* Any other headers your browser sends
* Metadata about the page itself that the publisher publishes via "og:" tags
Said og: tags look like this:
<meta property="og:title" content="Facebook ordered to stop collecting user data by Belgian court"/>
How does that compare with what you meant by "obscene amount of personal data"?
