Facebook Yelps

Posted here (week 1758).

Facebook’s new advertising model includes publication of activity from partner sites in news feeds. Their official list of affiliates does not include Yelp, but tonight, I had a little DHTML “toast” pop-up inform me my latest review would be shared on my Facebook profile.

A little investigating shows that this was pulled off via a JavaScript include, http://www.facebook.com/beacon/beacon.js.php and there’s already a bit of kerfuffle about it.

It does appear that authentication is being handled entirely via facebook.com cookies, and participating in this integration requires they recognize your site as a registered source.
