Need help with twitter-code!

what i want to know is, what am i doing wrong?

You haven't told us what that code actually does. You haven't told us how that differs from what you expect. Yet, you want us to tell you why what the code does is different from what you expect, and how to fix it. I think that is not going to be possible.

since i have no switch connected yet (will add them tomorrow) i expect to get the tweet "No

If you have no switch connected, you should not be trying to read the state of the pin. Since you have not enabled the internal pullup resistor, with nothing connected the pin floats. It's state is not defined.

When you do connect the switch, don't forget the external pullup or pulldown resistors. Or, make life easy, use the internal pullup (digitalWrite(pin, HIGH); after the pinMode() call) and connect the switch to the pin and to ground.
