I understand that the refinement of any tools to streamline and adjust Habr continues in a permanent mode. BUT:
Do not lay us a non-system component with an unpredictable action?
Well, for fun, as they say all sorts of things - "for fun".
The simplest idea: Habrahischnik, secret, unobtrusive habrassiness, which can bite off a piece of habrakarma from a random user, devour a blog entry, and so on - cause some unpredictable symbolic damage. In this case, of course, the actions of this monster should be documented like:
Pupkin's user has 3 karma bites off
This idea can be developed further - for example, habraangel.
Stand out for discussion.
