Its good that the counts are being noticed...one thing that has always bugged the hell out of me is the fact that "default" themes are on that list by default and takes away any chances for theme authors to reach the top spots. I don't think the default themes should be allowed on there...it's like WP saying it's our list and directory, so we get to have our cake and you get the crumbs. Eventually, as more default themes are added to WP, the list will be all default themes! Perhaps a bit exaggerated, but this is how it appears.
