    This is absolutely the best tutorial on using SPARQL to query Wikidata. 2 hours of your life is nothing compared to the perfectly paced lesson you will get. There are no shortcuts in life or programming. Thank you for this great video!

    This video's long, but I watched through it because the guy is pretty funny in certain cases. He knows a good balance of comedy and professionalism.

    "if you are really proud of this query, because it now includes some complicated syntax and we want to share it with our grandmother or something.."
    The funniest thing about the joke is how smooth he is.

      it's functional on Mac as well, you must go on control + space and write down something.

    Excellent intro to RDF. Regarding "fathers of politician" -- isn't father a subclass of parent? if so, then how would I refactor the query to be "parent-focused" (i.e. gender neutral) without resorting to UNION "mother of politician"?

    Why does this guy not have his own show in Las Vegas?
    I can't believe he took nearly two hours to present twenty minutes worth of information.
    If I had to research how to do this at work, I would miss a quarter of a day listening to a guy whose voice rarely deviated from second octave E natural.
