There's only one problem with the WordPress.com Stats plugin: editors can't see them in the dashboard, they have to go to the WordPress.com website. This is so even if I add the editor as an "administrator" in the Stats interface. This is the one complaint I have. I'm considering reinstalling Statpress because my poor editor, not being the techno-wonk that I am, isn't happy. I have the roles plugin, but unfortunately, it's not aware of the stats display.
