I was just chatting with a few alicebots there. They reminded me somewhat of eliza, the old AI “counselling” program. And text editor, for some reason. Somewhat better, but still not great. They still repeat what you say in some situations, which just makes them look stupid.
I was looking for VRML multi-user environments as well. There never seems to be many, whenever I look. I should start one (yeah right).
