Minus wisely

I often see that in some posts there is a “minus” and there are no comments to it.
And most often this situation happens with the posts of new habra people.
What could it say?
- The author of the minus is so disagree with this point of view that he did not even deign to comment on his assessment.
- The author can not comment on his point of view at all (I do not believe in this option).
- The author of the minus misunderstood the idea of ​​the author of the post.

Not that it would have bothered me much ... But it seems to me that it would be fairer if a window with an “obligatory” comment appeared before installing the minus.
And perhaps this window appears only when the “minus” karma is below a certain figure. Or from the time of registration less than a month.
This way you can catch newbies and tell them about their mistakes.


Pros:
- If the user has no worthy grounds for a “minus” his comment is jammed.
- Next time, before minus the habrachelovek will think about whether the reason for which he minus is so important.
- On the example of others, newcomers will be seen, for what and with what thoughts their posts are habraedi.
- As a consequence of all this - we will see an improvement in the quality of materials at Habré.

Minuses:
- A large number of odiankovye comments to frankly bad articles.
- Perhaps because of this, many will not minus the bad stati and then the quality of materials on the contrary will fall.

It will be when the thread on the site or not, in any case, it would be interesting to hear your opinion on this issue.
