Again, the scores amuse me :)
Laz has played with the algorithms a bit. Due to the fact people only tend to vote for stories they like, he has tried to apply a "curve" to scores to force them realistically lower. The hope was that readers, seeing stories they liked having scores like 7 or 8 (instead of all over 9), wouldn't be afraid to give lower scores themselves. And guess what? It worked! Laz has looked at the scores given lately, and changed the modifier. This has the effect of raising many of the scores for stories posted in the last two years. Mine included. So, if you look at my page and see more 8's than usual, it's not because the stories improved.
