It seems like just about everybody is on Twitter. That's both good and bad: you can keep up with your favorite celebrities, but that also means that there are those poor souls who literally do just answer the question "What are you doing?" So how do you keep everybody up-to-date on your latest activities and opinions? Sure you can post on Twitter's site, or you can use a third-party tool to tweet. How about your phone?
TwitterFone is a service that lets you call up and speak your message. The magic TwitterFone machine takes your message and translates if from speech to text, and then posts it to Twitter for you. You can also listen to your Twitter stream as well.
TwitterFone is still under development, and is currently in beta. In order to join this service, you have to get an invitation from them. Submit your request on the site, and then just sit back and wait for the secret sign-up code to come your way. No decoder ring necessary.
