If you haven’t yet come across David Crystal’s blog, you might want to look at his thoughts on texting acronyms and their effects or rather non effects on the language. And if you’re not interested in rofling, there’s bound to turn up something of interest for anyone curious about language usage.
Quirky, precise, always entertaining, and still a prolific author, Crystal is a wonder of the English language world.

My favourite books by him are Stories of English and the beautifully illustrated The Cambridge Encylopedia of Language (3rd Edition).
