As you may know Twitter allows to post and receive messages via web interface, IM and SMS. Recently I configured my Psi to use twitter over GTalk. Today I found a way to integrate Skype with Twitter – Twitter4Skype. According to Japanese receipt you have to add an user Twitter4Skype into your Skype contact list, open a chat with it and send command
