2. Create or designate some sections as "serious discussion" sections, with no signatures.
This is actually something I was going to suggest.
I'd support this idea.
The section can also be used to test the impact of globally removing signatures.
How about we trial a sub board of bitcoin discussion where posts in there don't count towards activity or post count and signatures aren't displayed at all?
Removing certain sections from contributing to activity/post counts has been discussed in the past, but never was integrated.
Was there a reason this discussion vanished/idea was dropped?
