In Dashboard, there is a "Right Now At a Glance" which show the total number of post, comment, tag, etc.
I suggest to make a widget to show those stat.
i have a own-hosted wordpress blog which show those stat to my visitor. (http://www.kansir.com) "There are currently 650 posts and 628 comments, contained within 17 categories and 429 tags."
I want this stat too, but not only the hit rate.
The blog I need help with is kansir.wordpress.com.
