[Here's a page that displays your Meta stats and can track differences.][1]

It uses `localStorage` to keep a record between browser sessions and highlights any changed values.  For example this user just got an upvote on that raised a question's score from 7 to 8:

![Results showing change][2]][3] 

The page also takes URL parameters, EG:

    http://jsbin.com/ximuhuzo/1?poll=no&interval=77&sitename=meta.stackoverflow&userid=2963652


----------
**Please note:**

 - Currently, the saved baseline is updated every time data is fetched.  
  So, **if polling is enabled, the change highlighting will only appear for one poll interval.**  
  This will be the next thing I change if I make any enhancements to this page/app.
 - The Last "Active" date-time values are currently [raw Unix time from the API][4]. I'll format them in the next release.
 - For now, current totals are shown rather than delta values.
