Companie like Yahoo and Google built their business around web software. Just like any other software company, they tend to have patterns of practices which they utilize over and over again to ensure consistency across platforms and services.
A user tends to feel more comfortable if they use software that they are used to. I was a bit surprised that Yahoo is opening up their UI libraries to the world.
