To answer the op "best and worst" aspect:
Best - no not really. I read the M threads and most left me cold. A lot of the "nice" comments seemed rather sentimental and not "genuine" in the sense of grounded fact/reality as it was all based on media fed info and our own parenting "worst nightmare" fears. Not saying the comments were meaningless, just not really representing the best mumnset can offer us.
The best of mumsnet for me (and obv. subjective) involves wading a little further back in time to a handful of memorable threads supporting and caring about different people and their families through crisis and celebrations. Also those hilarious ones about all sorts of nonsense that just flows along in the moment.
Worst - unfortunately they have scraped the bottom of mumsnet and this is bad but just one of many examples to be found over the last 6 months or so. What a wide bottom mumnset seems to have right now too I find it harder and harder to find a lengthy thread that doesn?t contain spite/hatred/judgmental statements/lashing out/thoughtless and hurtful opinions. While the dreaded moldie threads caused a lot of hurt and upset, I am beginning to understand why some left even if still not impressed with the "how" they did it. If mumsnet doesn?t "buck up" soon and stop a lot of the disgraceful threads in the name of debate and "entitled to our opinions sod the lot of you" attitude then I imagine more and more longer term members will be tempted to drift off. I have been around since 2002 in one shape or another, drifting off, returning, lurking, posting loads etc and wonder if this latest drifting off of mine might be signalling a more definite change away. Mumsnet is supposed to be about support, having a laugh, debating, disagreeing, agreeing, sharing, learning, coping, caring. Right now is feels edgy, judgemental, over opinionated and at times very callous. This is turning into a rant but not intended. My tone is more of a sad, reflective, slightly disappointed one.
inscotland put it far more effectively than me - I too am all for a good debate and agree that we will never agree on everything - part of the attraction of the place. However yesterday was a total disgrace. Glad to see Justine wisely pulled the plug on it when she did. Some of those posters should be thoroughly ashamed of themselves.
End of rant - apologies for lengthy post. I needed to get that lot off my chest as been building up for a while!
