Our ABC has a Standing Committee on Spoken English, SCOSE. It publishes guidelines for ABC broadcasters about correct English, standards, foreign pronunciations etc. I assume this very useful little guide is published online by SCOSE. I am afraid I read every page, sad hey. But given most bloggers are quite literate, I think you may enjoy ABC Radio National Online Style Guide. The writer does not take him/herself to seriously. A snip follows.
a listener has kindly pointed out that 'foetus' is not the correct spelling according to the British Medical Association. That's good enough for us.
