voted maybe/other. There may be other (perhaps additional) options to reduce clutter and make for easier reading.
The question is how do you reduce noise and increase quality of postings. To better group posts by threads is only partly addressing this, but with the volume of topic developments and overlaps as well as an increase in posters it's going to be hard to execute.
And therefore I do remain of the opinion that it's at the poster level there needs to be better controls, not only postings. Providing a thread (or more) for the guys who we all know shape opinion here and have inside links/info, are connected, etc is one option. Better moderation another, but again hard to do.
Maybe can look also at how other forums resolve this issue; can't be unique to CN, must be some best practice out there, if not, maybe an opportunity to experiment here at the clinic.
