On the GullFoss blog, Matthias Mueller-Prove has bravely assembled a nice graphic of users in the various OpenOffice.org sub projects. Makes for a great graphic and on first blush one does think it does tell you something.
However, Matthias immediately came under critic that the number of members signed up in the OpenOffice.org project website tells little about involvement and most likely contains a load of “dead” members. and Matthias readily admitted that this might be so. He volunteered to assemble a similar graphic with better data if someone could point to a better metric. If you have an idea, please help him out.
