gist embed

I just noticed that you can embed gists by pasting the url to the gist into the post editor on a line of its own. This uses the shortcode module of the Jetpack plugin so you need to Active the plugin and then the shortcode module.

this example is an applescript that creates auto-complete gifs for google searches. Not something many folk would need.
