Feeling Mirth-ful?

Laughingstock or laughing all the way to the bank?

Groupon may be passé, but that isn't stopping anyone from trying to cash in on our collective appetite for restaurant discounts — the latest effort is something called Mirth, as TechCrunch writes. When you sign up, Mirth takes down your credit card number and then as soon as you dine somewhere more than once in a month, you become a "regular" and receive a 3 percent discount. At this point the restaurant also gets your info, so they can send you coupons and alert you to specials, which sounds potentially spammy, if you ask us. Grub readers, would you sign up for something like this? [TechCrunch]
