Naturally, change doesn't look so appealing, so when this feature was introduced I didn't like it either. However, when I understood the meaning behind it I liked it very much. It's another way of expressing the forum's appreciation to its members' contributions. You get points based on your participation in other people's topics as well as your own topics...
The # of posts is just mere statistics... but the # of points is saying thank you to the members. I got the impression that my forum members liked it.
