Barth is not just popular amongst liberals or some post-modern evangelicals. He is very popular in many "Evangelical" seminaries, and I know for a fact his thoughts are the main influences in many of the Asian Protestant Seminaries. Even when people don't quote Barth, but (like the recent WTS seminary controversy) there will be people that sounds very suspiciously like Barth. The genius of Barth is that people take him to be a great defender of the faith, against the scholars, and views him as some champion of Protestantism. Face it, you can a poll today in Protestant churches and there will probably be 10 times more people that knows Barth versus Warfield + Hodge + Turrentin.

While we are well aware of his errors, but they do sound too good and too easy to use to defend Protestant faith against "difficulties."
