Hi All,
I've been working on visualizing editor behaviour on wikipedia over the past few months. Below is the first set of graphs & some of the results.
Some numbers about the graphs.
  • For the graphs showing data from 'en' - the english wikipedia I crunched 790~ million edits and turned it into a 180 * 180 matrix of data.
  • All the graphs are plotted from this 180 * 180 matrix, so it might take a few seconds to load.
  • The graphs are interactive, they have a filter on the top of the page. Play with them.
Some preliminary results
  • The monthly decline in active editors in en may be attributed to the old timers. We see this across other languages too.
  • Only the articles in the (beginning - 2007) cohorts continue to see active edit activity.
  • Retention rates are much higher in languages like de.
  • zh (continues to show uptrend on many fronts. Active Editors, retention etc).
