I was there for that stream; I'd suggest others watch the chat replay before deciding whether the results of any poll taken during that stream are credible.
I have to wonder how many people that voted even know what WordPress is or even use it. It’s easy to click a button on the screen to vote one way or another during a stream while being completely uninformed.
Sure it’s in use by a large portion of websites (43% I think I saw last) but that doesn’t mean that 43% of people know what WordPress is.
That stream wasn’t on a WordPress-centric channel.
