- There's a fascinating post on the Habitat Chronicles, the blog of virtual world pioneers Chip Morningstar and Randy Farmer (creators of the '80s LucasArts virtual world), which discusses context-sensitive fixed word chatting in virtual worlds, as currently used in Toontown for Disney to avoid unfortunate 'To Catch A Predator' situations.

They relate an attempted project for Disney in the '90s: "We spent several weeks building a UI that used pop-downs to construct sentences, and only had completely harmless words - the standard parts of grammar and safe nouns like cars, animals, and objects in the world... We thought it was the perfect solution, until we set our first 14-year old boy down in front of it. Within minutes he'd created the following sentence: I want to stick my long-necked Giraffe up your fluffy white bunny.""

But they go on to discuss convoluted ways around the fact that you need a 'secret friends code' to directly talk to people you meet in-world: "Another way to make secret friends with toons you don't know is to form letters/numbers with the picture frames in your house. Around you may see toons who have alot of picture frames at their toon estates, they are usually looking for secret friends." Then they arrange the pictures to make letters and... wow.
