The logic of weight degradation should be changed

[kkamkou]

Problem: Right now a repo which is in trend for a long time has an abnormally high number (example: 50). To become a "hopeless" repository it would need a long time (months or even a year).

Options:

• Decrease weight in Fibonacci manner (-1, -2, -3, -5, -8, etc.)
