Instead of lamenting the declining discourse, I suggest ignoring trolls and engaging with people who are sharing useful information. There are still some here.
It's a reasonable counter. For me, it got to a point where getting past the noise to get to the signal became work and it wasn't fun to come here anymore. So I stopped posting and went to the chatroom during games. And then that stopped being enjoyable, so I stopped coming to the site altogether.
When the forum gets an upgrade, an ignore feature would help tremendously. Until then, if I choose to keep posting, I'll do my best to ignore trolls, people auditioning to be Colin Cowherd's sidekick, and those speaking Authentic Frontier Gibberish. It's lonely out here for a Bobcat and really easy to get disconnected when you're so far away.
