This article describes how the scoring system work in Yahoo! Answers and explains the points worth.

To thank the Yahoo! Answers community for great answers, we give points for various actions. Answers points help you build your reputation on Yahoo! Answers and show the world what you have to offer. You need points to ask a question, but you can quickly earn the points back when you resolve your question and by giving answers that are picked as the best answer.

The points table summarizes how many points you get for each of the different actions you take. The points allow the community to recognize how active and helpful you've been, and they give you another excuse to brag to your friends.

The levels mark your activity and show what Answers usage privileges you earned. The more points you accumulate, the higher your level, and the more privileges you get. We're planning some exciting things for Yahoo! Answers, so stay tuned!
