Thread:Talk:Article feedback/31 May 2011/reply (22)

We don't have data on anonymous readers -- we don't track what our users read. We've considered using some metric like time-to-rate (time between page load and ratings submission), but that was a lower priority than capturing just the basic information.

On the research page, there is data on the article length distribution of the one of the earlier sets (727 articles as of Feb 2011 = PPI + additional articles).

Revision length at the time of rating submission is captured. Please feel free to dig into the data.
