Yes, I noticed that. I haven't been on the forum in a while and I was getting 20 points per post when I first joined, now it has already dropped to 10 points. Presumably at some point it will halve again, not sure of the exact timescale it works to (think I did notice something on one of the threads, but can't remember where??), but creates an incentive to remain active on the forum and make useful contributions. Most of the threads don't seem to get above a few replies, which is a shame. Need it to be active and informative to build the number of users.
