Visualising Nutch mailing-lists traffic

The graph below show the traffic on the Nutch dev and user mailing lists (http://mail-archives.apache.org/mod_mbox/nutch-user/ and http://mail-archives.apache.org/mod_mbox/nutch-dev/) from March 05 to August 11.

Traffic on Nutch mailing lists

(large size version of the graph here)

Unsurprisingly the traffic on the two lists follows similar trends with ups and downs and the user list globally more active than the dev list, apart from a period in 2005 (early Nutch development), a peak in July 2010 (discussions around Nutch 2.0 and refactoring of code) and the last few months. The figures for September are not complete but seem to confirm that Nutch is definitely back to a level of activity which has not been seen for the last 5 years.
