Abbreviations

Everyone uses abbreviations lately when talking to eachother.  They say TTYL, LOL, GTG, HMU...etc.  The funny thing is though, I never see anyone use what was probably the first abbreviation that could be used for conversation. TTFN..ring a bell?  You know, Tigger!  From Winnie The Pooh!  Yea, Ta Ta For Now!!!  How could that be forgotten?  I may just start using that from now on..ta ta for now! :)
