I love statistics and as most forums admins will know, when you're trying to build up your forum it really helps to know as much as possible about the people who are viewing your content. I was looking around at what all the main forum companies as well as blog hosts offer and the best (and nearest to what I'd like to see) set of statistics which is offered can be found on Blogger.
This is their overview page:

As you can see it's pretty clean cut, you can select to view not only the table with pageviews but the entire overview page by a length of time (i've selected week).
I'd love to see something like this for XenForo, although notable changes would instead of Posts become Threads and would hopefully also include an extra page with statistics on number of members, threads, registrations and other helpful things. Blogger also has a page in this statistics sets telling you about the browser and computer your readers use and I think this would be invaluable for forum owners who make modifactions to their forums, no one wants to alienate a significant portion of their members by adding a modification that can;t be used by a certain browser or whatever.
Anyway like if you like, say if you don't.
