I'm not an academic, so don't spend many hours a week reading and thinking about papers. And even back when I was a grad student, I wouldn't have been willing to bear all the weight of making all these discussions happen by myself.

But some subreddits, like r/MachineLearning, have gotten us off the ground at least.
