Why is the SDMB membership declining, and what's the best way to add younger members?

Excellent example. I originally thought of discussions as potentially endless, but soon realized… those long, long discussions aren’t tenable:

We’re going to add a limited form of real-time chat to take some pressure off certain “topics” that degenerate into chatrooms.

Yeah, devolving into the standard “things people commonly argue about” template is a problem with general discussion topics. Maybe take it as a challenge – can you start an interesting, unique discussion that avoids repeating all the standard arguments about hot button issues?

On another site similar to this one, the site owners do regularly post topics for discussion every day. There is a vast divide between the “difficult” (race, gender, guns. etc) topics and the “easy” ones. But you need new topics … and some discipline around keeping the discussion on those specific topics, plus or minus 20%.

Pick the weird, obscure, strange stuff to discuss!

This one is difficult from a tooling perspective. On our oldest Discourse community, one of the few remaining sore points is when a long time user suddenly goes “on tilt”, per the poker term… we sandbox new users so they can’t post too much, for everyone’s safety, but established users can reply as much as they want.

We do have Slow Mode, which allows you to limit a discussion to one reply per person per (x) minutes. That at least prevents the “I now shall reply to every single person in this topic and explain, in detail, why they are wrong” phenomenon.

Hmm. Can you provide a few examples? With names removed to protect the innocent.
