We all know that if Google really wants to make something great, they focus on the project and create something different, unique and usually better than what others have. GMail ,Picasa, Maps and Earth are just a few examples that show why Google is such a big shot. But then there are Google projects that clearly don't get enough attention and thus can't compete with the competitors.
Orkut may be big in countries like Brazil and India but globally, it's nowhere near Facebook. I wonder why Google doesn't try harder. Maybe it's working on something big. Something that has a service like Facebook integrated.
Okay the "big thing" is Google Wave. It can kill Facebook!
