FAQ 279 ("How can I wrangle Facebook into posting on my wall whenever I post on LJ?") seems to be out of date. It looks like Facebook has changed its privacy setting since the FAQ was written. I can't find a "Privacy Settings for Third-Party Websites" setting at Facebook.com; instead, it seems to have been moved to http://www.facebook.com/editapps.php?v=wall.
Also, http://www.facebook.com/beacon/faq.php seems to do a better job of explaining the Beacon popup than we do (for instance, "toast" is not a very good description of a popup, I don't think); since this is an external feature, can we link to the external documenation of it with a sufficient disclaimer?
