How does this community feel about Yiddishism and the New Yiddish movement?

I’ve seen some of it, and learned a bit about it growing up, but I can’t tell it’s purpose. I have heard it being used to describe a revival of Yiddish culture, but so far it seems to be a mostly artistic movement. How do you guys feel about it? Are there any nuances and controversies surrounding it I should be aware of?
