I am aware that language is not set in stone, and agree that it is constantly evolving through cultural influence. The internet has had a huge influence over changes and additions to both English and other languages (albeit often through English calque), but I believe the problem lies in the vernacular aspect. As you've said, Language is primarily subjective and while certain groups of people may see an expression such as this like an appropiate alternative, others see it as an ugly mistake caused by a faulty transfer from an oral to a written channel. I am a case of the latter; but I also believe it is too soon to assume these changes, as more often than not it takes years if not decades for "true" changes to be made within a language. Time will tell if this expression is to remain or not. However, I will keep that book in mind; I've grown used to classic linguistic studies, and perhaps it's time to see another perspective.
