Talk:TTFN
Appearance
TTFN is also the thing that Tigger (from Winnie The Pooh) uses whenever he says goodbye, and spins off on his tail.
Also in the movie Witchboard
In the very 80's horror movie Witchboard ([1]), there's also a freaky, young, female psychic using this initialism. In an ironic and self-centered way.
No easier to say, but easier to send
While TTFN may be no easier to speak than Ta Ta For Now, it is much easier to type, and therefore more useful in e-mail, SMS, or other electronic transmission, e.g. Morse code.
