Not because it brings out the dirty bad sad side of MN.
Not because there are lots of fights.
Not because people use it as an excuse to be foul ("well, this is AIBU - what did you expect sucker?")
Just because it makes us look like a bunch of ignorant cnuts.
Every type of subject under the sun gets posted in AIBU. People have not really grasped the concept/thinking behind it.
So when you get titles like AIBU to ask what is your favourite colour/biscuit/film and other similar general nonsense questions ad infinitum
then
it just makes Mumsnet look like a VERY dumbed-down site indeed.
Thanks.
