Have you ever wanted to give someone your phone number without actually giving them your number? For example, suppose you're listing an item on eBay or Craigslist. You want prospective buyers to be able to reach you, but you don't want your phone number posted online for all the world to see.

Enter , an ingenious service that turns your phone number into a safe, disposable Web link.

Here's how it works: After entering your phone number on the Babble.ly site (which promises total privacy), you get a unique Web address you can share as needed. When a prospective caller clicks the link, he/she is then prompted to enter his/her own number. From there, Babble.ly calls you both, then connects the two calls. Your number is never revealed to the other party. Clever, huh?

When you're done, you can keep the link for future use or just delete it.
