I don't know Sniktaw ...it may cut down on some of the "post and delete" trash people sometimes send me :)
It may allay your concerns recent  about "rigged voting".

People have an expanded number of ways to react to unpleasant comments besides an anonymous "vote" button.
True you run the hazard of having people beside your regular ":pals" here reviewing what you say...that sounds like a good thing...no?
You may even get (internally) scored over time on what you consider to be a civil comment or not...that should not be hard.

The upside potential is limitless.
The idea that some might (at this point) decamp as a result occurred to me as well... almost immediately, so I can't say I am completely surprised by your news...
Stick around...I would like to see how it turns out for you.
The flip side of this is that it may get market contrarians (like me) voted off the comments section...
Your wish come true.

Personally this is good news on the scale of seeing rates go up .5% recently....:)
