Reputation, credits, or points are fairly common among forums. Most forums provide a simple gamification where you post a reply, you earn a point. You write a new thread, you earn 3 points. On Reddit, you can earn Karma.
These points are cumulative, and never disappear. However, the whole point of reputation is not just their overall sense of contribution, but their contribution in a period of time.
As an extreme example, imagine a user who was active and posted 10 years ago and who earned several hundred points. But if they havent posted or participated in the last 10 years, how useful or relevant do her points mean to the members today?
We should decay points or reputation over time. Reputation must offer relevance and timeliness to stay important.
