facebook quick hit

One of those things I should have guessed I could have Googled for earlier... sometimes I get frustrated when I go to post a link to my just-updated site and the Facebook preview is out of date, the cache hasn't been updated. One hack solution might have been to add a meaningless "?foobar" to the end of the URL, so FB got it fresh, but that's problematic for several reasons. The correct solution is to go to the Facebook debugger page which presents options to do a new scrape, explains how to control the meta-info it grabs, and a few other things.
