I'm not going to argue that textese should become the language of scholarly writing. I never use it myself, even when I am texting. That said, I do imagine it could, much like short hand writing, have a legitimate place wherein it could have some advantages. Not only that, I suspect that as time goes by we will actually see some of these text words become integrated into the primary language, simply because they are used so frequently. The fact that it has no place in scholarly writing right now is not a complete argument, because it doesn't take into account the fact that languages change over time.
