Colleen Lee and Gregory Misiorek: don't get me wrong.
I don't criticize that some users don't down-rate content or others that do this.
What I wanted to point out was: the points system doesn't help to reduce low-quality contributions.
The comment about not saying anything if it is not nice surely is spot on.
Providing feedback that is not "like" or "very good" is much much harder and more difficult than the positive or non-feedback option.
It's easily possible to applaud, it's easily possible to say nothing (ignoring is barely possible, since a page view is counted independent from the readers reception) but disagreement is difficult.
To me this seems to be a rather strong voluntary design decision for SCN as a communication platform.
This in turn is the reason for this thread: since just passing on the things that we don't like in SCN is the (new?) standard, I thought I'd ask you on your view on that.
Thanks for contributing!
Cheers, Larrs
