I am more bemused by this than I should be and have to share: http://www.w3.org/TR/2010/WD-emotionml-20100729/
I'm trying to come up with some reasonable use of this, and all I can come up with is some sort of metaverse or semantic web application. But I don't think I'd want to code in it... the variables are too wide! Anyone else have some ideas about how this might be used in current or future applications?
