Engagement via Youtube

Every election campaign now involves Youtube, it seems almost de rigeur and normal. There are not many questions uploaded yet and not much activity but as the contest moves towards a conclusion it could be interesting to see how many engage with the three main candidates and want to talk about issues. Currently it is just the 'wall' that is gaining attention, here we find issue based questions some of which border on the philosophical to some extent i.e.: "Is it right that an indigenous population should be allowed to become an ethnic minority in their own city without even being consulted?" but then we have social media graffiti a la: 'BORIS IS A CUNT' a weighty contribution from someone called Pete. But, that aside, is Youtube offering a real potential for a new level of engagement or is it just a passing fad that only a few will bother with - an interesting question!!
