AOL is giving away phone numbers with AIM Phone Line for free and that's a great way for people to start creating what I have tabbed Shadow Numbers. Now you can give someone your number and never have to worry that if you want to break of talking with them that your real number ever gets known. Can you see a huge opportunity in the dating market for companies like LavaLife and Match.com. I can.
Now United Online has responded with Private Phone, a me too offering, but with a twist. You can call in to get the new number. Smart.
