There's also a large group that feels discussion of other Users is vital to the commentary. ..
Oh my God. And frankly, I would be surprised to learn that group is "large". Because in recent years, we've heard from fewer than 10 users who feel other users have sinister "motives" that need to be exposed. Up till now, posts that purport to advance that kind of exposure have been strongly discouraged, and deleted as either off topic or personal attack.
As they should be. A poster's supposed "motives" for posting as he does can only be guessed at. One thing's for sure: whatever they are, they will NOT affect the performance of the stock in question.
So please give up this idea. It will only cause a precipitous decline in the quality of some boards. And it may also encourage some members to deal in genuine defamation. Which I'm sure you don't want.
You do not need to accommodate really stupid ideas. Nobody wants that, except for the people who propose their adoption..
