sorry, i guess being in japan and all, i'm late to get into the whole LOLcats thing, but after checking out these guidelines:
http://icanhascheezburger.com/2007/04/24/lol-kitteh-as-a-second-language-lksl-101-in-five-easy-steps/ i thought it raised an interesting linguistic question. it's a bit similar to that not-so-recent, not-so-old study about how people can reasonably decipher words liek thsi adn actlluay not notcie thme unlsse tehre's too many of them.
i've been out of the linguistics loop for about 3 years now, but maybe there's someone out there doing research on this? especially in light of countless programs trying to ban/filter all kinds of words and their misspellings. i suppose it's just the evolution of l33t? but at what point does it get entirely unintelligible? it there a fixed breaking point?
even beyond misspellings, the grammar also appears to be teh wreckedness. but given the famous example:
Colorless green dreams sleep furiously.
vs.
Sleep dream green colorless furiously.
vs.
dreamsitude oh ur greenocity tewtally ooc teh sleepiez nite zzzz...
the LOLcat grammar does follow some rules, and i guess at this point it becomes more a pragmatic rather than syntactic question in that the intelligibility of the text relies on how it deliberately flouts grammar by using grammar.
