OT: Do you by chance have any pointers on where to stay up-to-date on modern frontend development?

As a dev I've been out of the frontend game for a few years, when BEM was widely used. When I started working more on frontend again a few months ago I tried to look around for developments in terms of methodologies (e.g. "is there a 'next BEM'?"), but didn't really find anything and didn't even know where to look. Even just hearing about newer aproaches like CUBE would be nice, regardless if they end up being fit for production usage.
