I would be very disappointed if McD adverised on mumsnet.
Yes, we're all adults but their ads appearing on MN would give McD certain validation to a company that does NOT represent the ethos that I have associated with MN over the last 9 years that I have been posting.
Mumsnet is where I first heard about the book 'The food we give our children' which literally changed my whole outlook to kids' food, well before Jamie started his school dinners crusade. MN taught me about sunny delight, fruitshoots, the hazards of uncut grapes(!) and also gave me the confidence to actually ignore the advertising aimed at first time mums (which I was at the time I found MN).
And I'm not stupid... but I honestly thought that there wasn't much of an informed choice when it came to kids' food and nutrition. Looking back I was very very naive (go figure!) but I grew up without a mum, with very few female role models who were mums themselves and I was pissing about it the dark for that first year, depending on baby books and crappy parenting magazines that were given to me.
MN showed me there was an alternative to the type of parenting I saw in mags and in adverts and I'm so bloody grateful that I found it that one day I was googling for high chairs 9 years ago.
If it had been plastered with McD adverts, I honestly think I might not have stayed very long after reading my highchair reviews: it would have just been another one of the many run-of-the-mill, coporate-driven websites that I was seeing at the time.
