Thank you Ms. Koslyn and Mr. Ballard for you timely responses.
To further clarify, the song is about a scorned woman who uses technology to stalk her ex-lover. "Twitter" is a direct reference to the use of the twitter.com application to help her to follow him around. I also refer to Blackberry, Facebook, Caller ID and GPS. The "tweet, tweet" (background vocals) refers to receiving or sending a "tweet" using Twitter. I just want to make sure that it is understood by both of you that I am actually referring to this and other applications.
