Twitter goes Vocal

Voice-calls come to Twitter today. Check out this CNN story on the new Twitter application:

According to Jajah, an Internet communications provider with tens of millions of users, the service will allow a user to place a call to any other user, so long as the second person follows the first on Twitter and both have Jajah accounts.

The service is free to use and is expected to work on any Twitter-enabled device, from PCs to smart phones.

This follows on the heels of an announcement by Facebook that a third-party designer will be offering voice-communications for some applications at its site.
