I don't think it was you talking about dirty linen & stoically uncomplaining Blitz housewives, Alea. My comment was intended to support posters saying the internet provides much-needed support and information, as well as offering company and an escape. On the whole, I think it broadens our horizons - depending on how we use it!
There's a joke about if you could meet people from the past. You'd tell them:
"I have a device in my pocket that can access all of the information everywhere in the world, any time, anywhere, and can put me instantly in touch with millions of people!
"I use it to argue with strangers and look at pictures of kittens."

I fear we are not a happy cross section (see what I did there?) - I do!
People say the same about Mumsnet. Neither 'mums' nor 'grans' are as bad as the arguers on, say, Reddit or the Daily Mail comments. Maybe the world just is full of secretly grumpy, resentful people and the anonymity of the Web gives them courage to vent their unhappy thoughts? In the not-so-good old days, I bet they'd have been chortling at the latest hanging or ducking, and snitching on their neighbours to the priest.
Fortunately, there are lots of lovely, kind, clever & funny people online, too.
