Must admit... reading plain English is a helluva lot easier (albeit with the odd inclusion of slang composite words like "helluva") than almost pure SMS! But the hardest of all to decipher is really
bad spelling of normal English words combined with SMS (or attempts at SMS; or individual renditions of SMS).
I remember one guy on the MRT forums a while back, who put a good effort into typing entirely in a form of Oz bush slang... reading his posts was quite entertaining; more so if he was replying to a comical thread
.
Each to their own I guess.....
