I have been analyzing grow of community members in Drupal and from data (that counts people by the month of their first commit) which I attach below I see big increase in March 2011. I have started to look for the reason of this and have found that you had DrupalCon in Chicago where about 3,000 people had come. Is that the main reason, or there are any other reasons of this increase?

Would be glad to hear any suggestions

The more likely cause is the migration to git which meant:

  1. We were on a revision control system that was more "hip" than CVS (it's hard to compare the usage of these technologies, but google trends for common commands in each gives a sense that CVS is dying while git is growing)
  2. We made a policy change so that anyone who ticked the "I agree to these terms" Git Access agreement in their user profile on d.o could now commit code - previously people had to do that step AND get approval to be a full project maintainer.

There's some data and theorizing about the process on Aten Design Group - sand box projects at one month by Scott Reynen.

Greg, thanks for references

Greg, thanks for references and explanation, just for adjustment, so when the policy was changed and you migrated to the Git, these number of >350 users on March 2011 included only users who committed first time or also those who have committed earlier, but because of the policy change their commits also became "first"? (sorry, if question seems to be confused :))

Also, there was at least a

Also, there was at least a session by Sam in Chicago that had us to thru the git process, and I assume participants of the code sprints did the same, which could account for the higher number for that month...

The underlying data for this

The underlying data for this report looked for the first commits regardless of whether they were in CVS or git. I used the versioncontrol API database table and the data from CVS was all migrated into that system so that it shows only the first true commit for any individual user regardless of whether that commit was in git or CVS.
