I’m utterly fascinated with the CaPiTaLiZaTiOn that i see coming out of teen Friendster profiles and blogs in Singapore. But i so desperately want to know more. Does anyone know?

1) How does this work? Do people use the shift key to get that or is it somehow built in?
2) Why is it used? What does it mean?
3) Who all uses it? Age, location, etc.
