Personally, I keep tabs on the React forum, maintain my own React.js twitter list, and subscribe to the ReactJS subreddit. How do you all stay fresh with the quickly-changing React ecosystem?
For me, I do the same (twitter,reddit especially) but also articles on Medium or following the React.js node here on Hashnode....
