Ken is certainly an enthusiastic ambassador for the hobby.
As a gadfly, I'm sure he's a bit much to take for more than a few minutes, but as a modeler, he seems to produce some pretty good stuff. I've watched a few of his "What's Neat" videos, and frankly, they're insufferable. But his tutorials and project videos are kind of interesting.
As for the advertising snafu, these things happen.
