Why the lack of karma for the publication of the article affects the ability to save it as a draft?

MDA and questions with a negative rating and karma, too, ask not!!!
Amnesties are?

Well, as always, all the time. That's a very important thing for me now is a question that I think will best be able to solve the Habr-community. But Alas, karma is negative.

Hello dear Hebraically!
Decided to develop a system of "interactive floor" and faced the following problem.
The camera is looking at the projected image detects the movement of the animation like any other. And from this need to get rid of. Could you tell what it is better to try to achieve, hardware or software and try to analyze moving objects and to recognize a person which in principle greatly complicate the task. The idea was to use an infrared camera, but in this case, the question arises of the model, the price ( not big budget) and in General to have only theoretical understanding about donating the image. My camera Microsoft LifeCam v3000 pulled out the IR filter and the corresponding IR did not produce the expected results.
I really hope for a speedy resolution of this issue.

You can not write articles in drafts, not allowed to ask questions, it turns out the only way to raise karma is to Troll in the comments ??

Comments almost impossible to raise karma. But on the contrary very.

Put the advantages usually only comments/articles, cons and even put in karma.
