Erik Zachte, Data Analyst for the Wikimedia Foundation, has just released the first official public version of the Wikimedia Foundation's monthly report card on key program metrics. If you haven't seen it, his blog post about it is here: http://infodisiac.com/blog/2009/10/the-wikimedia-report-card/

And the public page is here: http://stats.wikimedia.org/reportcard/

What's being tracked right now is the following: * number of unique visitors to WMF projects according to comScore, with breakdown by region, and the percentage reach this represents among all Internet users; * number of page requests according to our server log data, with breakdown by language; * comScore rank relative to other web properties (we can't release all the data we have access to from comScore here); * number of content objects (pages, binaries), with breakdown by project for pages, and breakdown by filetype for binaries; * participation rates: new pages per day, edits per month, new editors per month, active editors making 5+ edits, very active editors making 100+ edits

We've used indexes as a tool to make trends easily understandable over time -- see the "indexed" tabs in the different sections. The top left of each section makes some key numbers easily accessible, e.g. month-to-month comparisons and year-to-year comparisons.

The report card will continue to evolve in response primarily to the Wikimedia Foundation's organizational priorities and needs - if we have a specific project designed to achieve impact in one category, we'll break out a section to look at it. And we're also hoping to have higher level summary information. Feedback is very much welcome - probably the best place to post it is in response to Erik's blog post above so we have it all in one place. :-) Aside from feedback, however, I also want to take this opportunity to praise Erik for all his work over many months in putting this together, as well has his ongoing work to release it on a regular basis.
