RedNote is a bit different: it has been wildly popular in China for a number of years, and the Chinese community has been using it overseas already.

It may not retain all the new users, but it is not going to become irrelevant.

I agree. But I'm just saying that #1 on the app store doesn't preclude something from being a fad and my guess is that in 1 month's time, no one is going to be talking about RedNote outside of Chinese communities.
