Do you think you can interpret student messages? I can't, and I'll be the first to admit none of that comes easily to me. Entering technology from the background of teaching English, I have an especially hard time using digitalk in any form. You might see me use a smiley to show that I'm trying to soften a message, but if I mean "you", I write or text YOU and not U. If I want to say "later", I type LATER rather than L8R. It's like forcing myself to say "ain't"--just can't do it without sounding affected.
For those of you who want to know some of the latest digitalk, take a look at the short list below from NetLingo. Some of it you may want to use, some you may need to know, and some are just good for a laugh.
