Google are idiotic for offering upwards of $5B for Groupon. Methinks Groupon will go the way of MySpace in not too distant a future. Other players and more compelling offerings will take its place, just as Facebook & Twitter did for social networking.
Instead, Google should pay IBM a cool $1/2 B for the science and technology behind Watson. Then spend another $500M adapting and scaling it for general use to augment their search technology and bringing it up-to-speed from the last decade!
Really I don’t care to get 100,000 search hits anymore. I’m only interested in an answer or at most 4-5 compelling answers in most cases.
