My gut instinct is that this deal was never on the table. The rational minds at Google would have to be high on something really strong to even consider Groupon worth $6B. (If so, please share, people!). My cynical thinking is that these were rumors spread by people interested in seeing Groupon go public; the $6B from Google rumor makes for a nice, fat initial offering price.<p>Groupon has zero barrier to entry and zero technology. Unless they have a strong IP portfolio (which they don't appear to be, given the number of competitors that have sprung up), I don't see the value here, other than brand name.<p>I was given a Groupon for a local specialty chocolate vendor recently, so I decided to chat her up to see what she felt about it. She had tried Groupon, Townhog and a couple of others. She shrugged and said that she wasn't sure if she was going to try these again; but if she did, she'd use Townhog. It was clear that there was no barrier for her to switch. Why should merchants give Groupon 50% of the face value of coupon, if their competitor will do the same for 25%? And the next one at 10%?
