If you want to have a private conversaion, social media doesn't seem to be a good vehicle for it. Much like airing your dirty laundry in the town square has been considered bad etiquette, airing personal greivances on the internet seems to be in poor taste.
It must be noted that manners never arise sponaniously in culture, but becuase people fear the consequences of breaching etiquette. I for one welcome the return of politeness to society.
I agree that it would be nice to see people imposing their views on others less - "Live and let live" is a basic requirement of a Liberal society. But the dystopian future evoked by this microsite is sort of the opposite of that - an enforced uniformity, where instead of tolerating difference we attack it until people learn to hide it more effectively.
