Where do you find your information? what blogs/people do you follow?

I am always trying to learn and better understand the tools that I use.

Searching through this forum and BSE, I always come across links to white papers on the latest theories and discoveries.
I am curious where do you find these papers? how do you know they even exist?

I am curious about who/what the “professional” or “advanced” users follow? Blogs, Twitter, FB etc.

Sorry I posted in the wrong section, couldn’t delete.
