Google Labs is a place where they incubate awesome ideas and features.
Then they launch it into the main project and people hate it.
Then they kill it.
You would hardly know how the typical consumer is going to use/like it from that data though (not that I do not agree that that might be a good idea, maybe they just want to get it out soon).
It's not necessarily about users liking them as much as just getting the features out before as many eyeballs and browser/system combos as possible before introducing them to the whole world.
