According to this

MOOs(Mud, Object Oriented) are online environments that grew out of text-based shared role playing games. They generally allow people to interact in real time in a virtual environment, where it is possible to create your environment--rooms, objects, and descriptions of characters.

Similar to a MUD, but the enabling software is written in an object-oriented manner, and generally focused more on programming than on games.

Yes, that's right! You can creat your own world on the web. The link I posted is one of the famous online university. You can go to the bar to order drinks. You also can go to library to read books, walk around the POD garden, watch TV in the Advanced Works Department. Just try, and you will realize that schmooze online university is alot better than the universities in the real world.
