OK it doesn’t exist yet, but that would be a cool app for phones and the Nokia Internet Tablet to have. Hellotxt is a web interface that allows you to log into your favorite microblogging services (if you have more than one), such as twitter, jaiku, pownce, facebook and so on, and it allows you to send the same status update to all of them.

The next level to this is the app. It’s local to your machine, you can log into all these services (just like a multiclient IM program), and you can not only send status updates to all your services, you can also receive status updates on your network from this client.

I wonder if they will ever make this app ;-)
