Bizzy: Local Recommendations
A bunch of companies are competing to tell you where to eat and shop-and one of them is Google, which recently launched Hotpot, a service that recommends local businesses based on the ratings you've assigned to places you've already visited. Bizzy takes a slightly different approach: You answer about 20 questions covering your favorite breakfast place, dive bar, or hair salon. Bizzy then crunches your data, finds people whose tastes match yours, and gives you the top picks of those like-minded users.
DooID: Controlled Sharing
If you give someone your contact information, you obviously want them to be able to reach you; but there are limits, and they vary. Your coworker can have your home phone number, but your needy new client can't. DooID makes that kind of nuanced sharing possible. You set up a profile that contains not only phone numbers and e-mail addresses, but also connections to AIM, Facebook, Twitter, and other social networks. You decide which parts are public and which private, and then share by giving people a Web address or a virtual business card, or by using a QR code. Supply those you trust with a password, and they can see all your information.
