For those of us who blog at WordPress.com, there’s already a shortcode making it easy to embed video from Flickr in a post. I’ll illustrate/test it with this clip, which looks to me like something from William Gibson.
I found the shortcode on the support forum, thanks to quxx/kellan. Like other WordPress.com shortcodes, it should be placed within square brackets. Then it’s just “flickr video=uri”. Note, by the way, that attribution for the video clip is built in to the clip itself.
