I posted my trading card using a picture of the 23 Things on a Stick participants at the MEMO Mid-winter conference. This was easy to generate too. I'm not sure I really like having open access to all of my photos however. I believe I will set my Flickr account to private after all of the 23 Things projects. I think kids may really enjoy this for History Day projects and/or biography studies. I would say there would have to be a lesson on copyright and posting images before this could be used.
