Savvy?

I'm talking about comprehension not Captain Jack Sparrow.

At what age is it acceptable to start ignoring the changes in language that comes with technology? Is it ever acceptable or should we just shut up and embrace it? Another language is emerging, made up almost entirely of letters and emoticons. I have the dubious honour of being listed in the MSN messenger contacts of an 11-year old (not mine). Her messaging technique is utterly infuriating. Conversations with her leave me feeling annoyed, and fucking old. I'm only 29.

(Speak of the devil, she's just popped up to say "Danny iz so sxc.")
