It's often a huge hassle to schedule a doctor's appointment, especially when you're super busy seeing just how many more toy trucks you can fit up your butt. Getting you in/them out in no time, ZocDoc, just launched in Philly.
Zoc's essentially OpenTable for the medical industry, cutting out the annoying "talking to people on phones" and helping you digitally discover area docs and specialists before easily booking an appointment with them, all developed by a UPenn grad-turned-programmer after he had to wait four days for an appointment post-bursting his eardrum, although it's quite possible he just didn't hear the receptionist say "sure, just stop by in an hour". Hit the site and give it your desired doctoral, dental, or specialty field, plus your zip/ insurance info, and it'll pull up a list of available MDs in your area and whether or not they accept your plan, along with providing user reviews and short bios, which you should definitely pay attention to if you don't want your own bio to cut off as quickly. Doc selected, give 'em a description of your symptoms, select an appointment time from the listings (which're awesomely often as soon as that very day) and create an account before confirming your time by text message, ensuring that no one over 50 ever makes their appointment.
Zoc's also got an iPhone app, which'll let you accomplish all of this from the palm of your hand, unless that's getting down to business with those trucks.
