I was thinking of doing the same thing, but I'm questioning how effective Reddit is, as a whole, in promoting genuine Epicurean discussion.
Given the nature of the way things are, my view is that there are lots of productive places to check in regularly, including Reddit, but with the goal of finding and moving good people to more productive places, not investing a lot of time and effort into too many platforms. But it's all a matter of time and resources, and Charles is a good example that if someone is into a particular venue, like Discord, it makes good sense to establish a beachhead there. But as long as a platform is ultimately under the control of people who would ultimately disapprove of Epicurean philosophy (and most of them are under the control of such people) it doesn't make sense to me to invest more effort than is appropriate to be sure that when new good people appear, we find them and re-channel them.
