Welcome - Moodle and Sakai and other other Open Source LMS implementations.

I enjoy seeing varieties of choices on Opensource LMS implementations. More research oriented universities will need something different form the universities that focus on general education. Or, K12 will need something different from Universities. (I am sure my 3 yr. old daughter is not going to learn 'A, B, C, ..' thru Bb/Moodle/Sakai :)). I would see it is the benefit for the campus CIO/CTO to get to decide what fits the university culture. That's why there are pedagogical difference between Moodle and Sakai in the design level and should be welcome. LMS is more than just a software - it is a platform for teaching and learning online. I would believe the birth of Moodle was Martin's implementation of 'the' idea for online teaching and learning. Why not Sakai or others?

Moodle's success is not mainly due to the PHP - it is the design concept and openness of Moodle!!
