Hi Joost, I was wondering about the statement attributed to you here:
"Because Moodle needs PHP to work, it's not as scalable as typical internet programming languages like Java and .NET. Moodle is good software to start gaining E-learning experience, but when things get bigger and more important, organisations tend to look at other, more scalable, software solutions."

You are aware that when Yahoo was looking for the most scalable solution for their website, they chose PHP?

I was at Michael Radwin's talk that year, the comparisons and testing they did was pretty impressive.
Do you know of any java/jsp sites the size of Yahoo? Any .NET sites?
NZVLE has projected out their load for ~350,000 users, and it seems like Moodle will be able to scale to that amount on a 4-5 boxen cluster.
