the problem for google is that 'searching' is not a social event. it is a personal thing. people dont search together. they search for stuff that they themselves want to know.
its completely different with facebook, because everything about facebook is social.
people click the 'like' button because they want it to appear on their wall for people to see. there is an actual point behind it. there is no point with the +1 button. people dont get anything out of it, other than helping google rate a site -- a site which they might never return to again in the lives.
google are trying to shoehorn in a load of social stuff where it doesnt fit.
