I think one of the reasons the Home product rubs me the wrong way is similar to the reason I resent junk-food companies for knowing exactly who their target consumer is, and building a product suited perfectly to taking advantage of the weaknesses of those consumers to move more of their product. Just like the way a nearby television broadcasting commercials starts loud and with a flash, designed to pull your eye in.
This product takes advantage of the brain's weakness for bright, shiny moving things, instant reward of an image flashing with a sound effect when you complete the desired action ("liking" something). Users won't be able to put it down. It feels cheap.
