Twitter should offer visitor statistics for a user's personal Twitter Page.

I would like to see per-user statistical information for people who visit your Twitter page. I'd like to see what Operating system and browser my visitors are using, what screen resolution they are using when viewing my twitter page, and their location. That way I can better tailor my background image to include pertinent information I'd like to share.

I'm sure others would find this handy as well. As many users employ a fake left sidebar on their background image to include their email address, contact number, profession, et cetera.
