This hole thing is kind of frightening. I'm not sure i like the philosophy here.
At any rate, those who find it comforting that 'big brother' is keeping the comments safe for them will stay around, and those with dissenting views will be banned to oblivion and eventually leave, making the community a small selection of people who both agree with the philosophy, and find it uncomfortable to deal with views that challenge their philosophy.
This is very similar to what happened in Academia in the past 30 years, and succeeded in pushing out all of the interesting, eccentric and creative people, leaving only those who knew the party line, and moderated their speech accordingly. I think this is not healthy for creativity, but then, that's just my opinion, and obviously the forum owner/moderators disagree.
And that's a fine and noble pursuit, however, the market place is not delicate academic utopia, and so one has to wonder how these very bright, but often impractical people, whose genius has been nurtured, pampered and flattered are going to deal with the realities of the market place and the end consumers of their 'product'.
Enter the Y-combinator business model, where for a mere 51% of your company, the harsh realities of business will be taken care of by our team of take-no-prisoners business warriors, leaving you, delicate genius, to be nurtured and cultivated to your fullest potential.
And again, I have no problem with that, I just have a problem with undemocratic secret societies that wield power from the shadows. They are prone to corruption and calcification.
