Well I'm new here today...only made a couple of posts and I don't see it as 'cliquey'...well not compared to a lot of other similar forums but time will tell Lol.
I think speculation is part of human nature...especially somewhere like an internet forum, but I do know what you mean. It can go a bit OTT at times. I remember when Madeline MCann was abducted...the forum I used to post on at the time went into meltdown with some really weir and whacky theories...but it takes all sorts to make a forum
The thing is no one on here has been spiteful and vindictive about the families involved, well maybe they have but not the posts I have seen. It is human nature to support but also to speculate, if something BIG happened on your street I am sure people would be outside talking about it, but equally offering blankets and essentials if their neighbours needed it.
I don't get how mumsnet can be cliquey? There is like a gadzillion of us all with different opinions. Mumsnet can at times be a big old hormonal argument, but not a clique, surely its too big and diverse?
