http://www.grammarphobia.com/qa is a site I visit on occassion for my own education. The Q & A list is just one feature. #32 I sought because I saw a poster on this board use the phrase in question. #33 is actually a question I sent to the author by e-mail and got a personal response, I bought her "Woe is I jr" for my daughter's english studies, and really even an adult might find something useful in it.
We used to have a poster that would launch a word of the week, or some other etymology related topic.
English is an evolving language, the only ones not evolving are the dead languages. One died last year as the last person speaking it croaked.
btw, # 32 was the phrase 'I couldn't care less' vs 'I could care less' for meaning you don't care
the answer surprised me, they are equal. I would have argued with the teacher or professor about that, but as I said the language evolves.
