If you've got the time, I'd like to get some reflective thought from you: Based on your glimpse, what did you learn about people, online communities, or morals and ethics that you believed or didn't consider before?
Otherwise I don't think I have special insight into people's morals and ethics. People remain complicated. You just get a better chance to see them in a different light when you expose them to a different medium.
Can't wait to see how people will behave in VR worlds, if it were to take off ;)
