Ben Brophy pointed out this at Google trends:
Where the red is Moodle and blue is Sakai:
But the graph for the United States is rather different:
Bear in mind that these are news reports which include the string ‘moodle’ or ‘sakai’. This can be misleading — it includes news reports about a Mr Sakai for example.
Jim Farmer’s comment is germane I think:
“What these statistics show is the different nature of the Moodle community and the Sakai partners. The Moodle community is predominantly teachers and faculty who are interested in implementation; the Sakai community continues to focus on software development. This difference was discussed at the April OSS Watch Conference in Oxford and deserves further study. My colleague Jon Allen is now beginning to analyze the difference in topics presented at the MoodleMoots and the Sakai conferences to see if it is significant. Another factor of the MoodleMoot success—more than 2,000 attended last year—is a combination of local meetings and low cost—factors that enable teachers and faculty to attend at their own expense.”
