The current space usage statistics could be improved in many ways. Ideally, they would display a rolling 1-day/week/month view (as opposed to viewing on Sunday and having 6/7-ths set to 0 views/edits) as well as a better display (see attachment screenshots from web-metric tool Mint) In addition, the ability to drill and cross-reference statistics would be of great benefit. An example of this could be viewing all edits by me for a particular date, then clicking on a page I have edited to reveal all other used that have edited that page that day/week/month/ever. Clicking on another user would reveal the pages they have edited, etc. This would need, obviously, to be integrated with the permissions system somehow.
