Shouldn't we be rapid-prototyping our ideas? Isn't that what "hackers" do often? "Hack" something together and then iterate like mad, failing fast on bad ideas and moving forward with the good ones?

I think a lot of us already see AngularJS as a development framework. A big part of developing something is also UX design. Do you have UX designers on your development team? I know that I do, and I can help sell Angular to them if they feel represented (as they should be).
