SiliconBeat has a story, “Jangl’s new angle on phone calling:”
Jangl is a new phone service that, initially anyway, will allow people to anonymize their phone numbers the same way they can their email addresses when posting on places such as craigslist. When you sign up with Jangl, you get access to disposable phone numbers that you can share with friends or strangers with whom you transact business. The phone numbers forward to your real number and anonymize in both directions.
Seems like a very cool idea. There’s lots of devils in the details, but I generated a one-shot email address to sign up for some one-shot phone numbers.
