To me, they are currently very different things with different qualities - I’m not sure I can provide an honest answer. I will personally participate in approximately the same way whether this is on gh, or a mailing list, or over here - but the discourse wasn’t about me it was about separating expectations and having a noisy and very open channel that is designed to serve that kind of need -gives you the tools for discussion, discoverability, search, thematic tagging, subscription, administration and so on. It’s possible, I suppose to achieve many of the same things via gh, but it changes several aspects of the equation too, so idk.
