Some research says that lurkers make up over 90% of online groups. I suspect that Less Wrong has an even higher percentage of lurkers than other online communities.

This made me think of how cool a LessWrong MOO would be. I went and looked at some Python-based MOOs, but they don't seem very usable. I'd guess that the LambdaMOO server is still the best, but the programming language is pretty bad compared to Python.
Some of the MOO's programming is pretty easy. I think I used to use something called cyber.
You would create your world by creating rooms and exits. With just the to you could create some nice areas. Note an exit from a room could be something like 'kill dragon'
It got more complex with key objects and automated objects but even with simple rooms and exits a person could be very creative.
