Mailing List Participation
The following plot (courtesy of Gmane), shows the steadily increasing post rate for cassandra-user during 2009. Note: There are two mailing lists (-user and -dev), but most traffic goes to -user regardless of topic.
Code Contributions
This plot shows the estimated number of unique contributors on a week-by-week basis. 
Similar to the plot above, this shows unique contributors, but broken down by month instead of week.
