If anyone is looking for slide material for a broad introduction to Wikidata, the deck from yesterday's New York City Wikidata workshop is available at http://www.slideshare.net/_emw/up-and-running-with-wikidata

There were at least 15 participants (with only a week's notice beforehand), and lots of interest in Wikidata.  Wikimedia NYC is a great crowd!
