Great video overall. And of course I especially love how he clicks on the leaf menu in the first seconds. 
And reads the user guide too.
I’m a bit surprised though that he’s wondering twice in the video (at least) if Haiku is still in active development. He does look around on the web site quite a bit in the beginning and the source activity is shown right there. What could we possibly do better here? He could have looked around a bit more and found the nightlies page, but I guess we don´t want to advertise this to new users more prominently.
