Each to their own I say. I've visited t'other site and found some warmhearted, caring responses on threads, but also the opposite with posters being belittled, ridiculed and challenged in very unhelpful ways. I did recommend the site to activistdaughter to have a look, but she'd rather get her advice from me (doesn't always take it).
She found the swearing on MN to be excessive and unnecessary - as do I.
I am glad that MN exists though because there do seem to be all sorts of posters and therefore a range of life experiences to share, and not all young mums have people in 'real life' they can open up to.
