Open Brainstorms

You'v seen Opentable.com - what do you think of the idea of Appointment Search for services?

What if you could search for "stylists", and see calendar with availability for dozens of stylists in your area over the next month? Would that be useful to you? What if you could do the same for mechanics, home contractors, house cleaning, and other services? From a business's perspective: If clients could schedule appointments with you online, would that help you grow your business? Would this service be compelling if it were free? You would remain in complete control of your calendar, and customer appointments would be secure. (Think of airline websites - they let you pick your seat, but don't reveal where anyone else is sitting)
