Hi, Dave says: Normally, Flickr sends back data in XML format, but when you add a query string, $format=JSON, we get that data back in JSON format.
But that should be ?format=JSON. He's just used to saying "dollar sign". It should be fixed in the video transcript, at least, right? Thanks. This is in video: https://teamtreehouse.com/library/ajax-basics/ajax-and-apis/beginning-the-project in the first 19 seconds.

You should report it using the instructions on the Support page. The staff might not notice it here.
