[Air-l] Laughter in CMC.

Hi all, Does anyone know of any sources that specifically examine the use of laughter in online communications (both 'lexically', as in 'lol' or 'haha', and through textual play, such as '::laughs::')? I'm looking for significant discussions of the use and interpretation of laughter, rather than just short descriptions devoted to this phenomenon within a larger piece of work.
