Jewish Action, the magazine of the OU, published an excellent article about the slowly brewing “trend” of Neo-Chassidus in mainstream Orthodox circles. There’s some fantastic quotes from Rav Moshe Weinberger in the article. Here’s one:
“Many of the off-the-derech youth,” he says, “are not running away from authentic Yiddishkeit; they simply never met it.”
The article touches on many different flavors and instruments within this trend. I know, as someone who as been hearing Rav Weinberger’s shiur for 17 years, that certain aspects of Neo-Chassidus work for me. The fact that the OU dedicated an article to it means that hundreds, if not thousands, in OU shuls and beyond might get a little insight into what makes so a bit more excited about their observance. The article can be found here.
Also, a close friend directed me to an interview with Rav Weinberger here.
