There was a small dispute about the downvote of newcomers with less than 110 point:
...the SE is supported by only a view enthusiasts. And they are doing this very well. But how to grow up more active people without giving them a chance to adopt to SE? It's really necessary to downvote somebody with less than 100 points?
...of course I agree... The question is certainly good and there is no reason to downvote it. It is just a duplicate, but its a good question.
And Countto10 brightens the situation
... but it is normal practice either to include some reference you read, but could not follow, or to give your own idea of what the problem involves.
So why not support newcomers and give them a chance to grow up? Why not establish a netquette about this or better not do give the possibility to downvote under zero? Ok, may be it should be possible if someone upvoted the question to downvote it to zero again, but I think this is contraproductive too.
