After a small correspondence with the developers of Habr, I had an idea for the site, which can help in the fight against the ministry , as the developers call it.
The problem is that some people like to minus, or they have a bad mood and they are minus, or they want to hurt and minus someone. In short, there are many reasons for minus (he himself is a sinner, I confess). And now, nothing is holding back habra users from minus. You can generally arrange some cons and no one plyusovat.
My idea is simple and, IMHO, quite falls into the stream of Web2.0 and the idea of self-regulation by users.
I propose to display in the user profile in addition to karma and habrasila also the balance of ratings (the sum of the pros and cons), which he put out for the last day / week / month.
If the pros put more than minuses - the number is positive. If there are more minuses than pluses - negative. The greater the number, the greater the gap between the pros and cons.
You can also make daily and monthly ratings - the main payers and the main minuses of the day and month. Perhaps this feature will make many people put less minuses and more pluses.
