I don't doubt that you've found a lot of people in your area who are interested in it. But it doesn't even imply that it's more popular than Angular in SE MI, much less anywhere else. You can't offer up another anecdote and pretend that it's data. And I'm sure you did fine work, but small business print shops are not exactly industry trend setters. What difference would it make in the bigger picture if you had chosen Handlebar for that project?
