Writers: Would you ever consider including emoticons in your writing?

[Alice in Wonderland]

Have you ever thought about it?

I've been thinking, people use it so much these days.
I mean, emoticons became a part of modern life and writing, so to say. Maybe some other people find it annoying. But they can't deny that they mostly serve their purpose.
Emoticons serve the purpose of communication, just like words, but:

What do you think would be pros and cons to this idea?
Would that degrade literature? Why (not)?
If such literature was to appear, would you start to divide it: high literature - the one that doesn't use emoticons and low literature - the one that uses it (just like in the old times )? Or maybe the standards would be opposite?

If you were to use it, when would you use it? Or would you replace all descriptions of emotions with emoticons? Where would be the limit?

Would you use it to express an idea?
E.g. I was thinking about writing some crazy urban futuristic novel where I'd use emoticons and abbreviations to express the degradation of communication and words in general (because, sadly, it's really happening). I mean, with this tempo, who knows what languages will look like in about 10-20 years from now. And didn't you ever say "lol" when talking to someone in person? I know I have. And I don't even use that abbreviation :/ How sad. Or OMG.

I think that's about it.
Again - looking forward to your answers
No, guys I'm not asking for your opinions on my story idea. I want to hear your answers on all those questions I asked. My idea was just an example so that you'd know what I mean.
