Odeo released a new service called Twttr, which is a sort of group send SMS application. Each person controls their own network of friends. When any of them send a text message to 40404, all of his or her friends see the message via sms. This launched officially today, and a few select insiders were playing with the service at the Valleyschwag party in San Francisco last night.
People are using it to send messages like Cleaning my apartment and Hungry. You can also add friends via text message, nudge friends, etc. It really a social network around text messaging – and is very similar to another service called Dodgeball.
Users can also post and view messages on the Twttr website, turn off text messages from certain people, turn off messages altogether, etc. There is also a status widget available that can be placed on a website.
