aitchtwooh, in answer to your question, I think any change in mumsnet (and yes, I did start a thread on this recently in relation to baby and toddler issues) is mainly down to what people post, the good manners, sense of humour of the individual posters. It is not governed by the names of the topics they choose.
'In the news' threads can also see lots of nasty comments at times. I don't think that is because the title is worded incorrectly.
