I assume Caitlin has younger children. The article and name checks have a babies/young children emphasis.
(Aitch and Hunker, though I know they post a lot here, do not figure so much in my experience of mumsnet as I block most baby and toddler threads).
It would have been good if there had been more mention of older children, education and teenager topics and a name check from someone like martianbishop or custardo, to reflect this.
If I had no idea about mumsnet, I'd assume from the article that it catered more for parents with young children and babies.
Can see there's an argument that if you cite thread examples, why not cite regular poster examples.
Still, anyone who 'knows' mumsnet would surely know that the name checks would go down badly with lots of people here.
IMO it would have been better to have writting more about memorable MN discussions, with passing reference to the backgrounds of those regular posters who appeared on them. Surely that would have got the personalities of the posters across in a less obvious way? But that's just my opinion
