Whenever I see a taboo, I just think that's something we need to drag screaming out into the light and discuss. Because taboos are where our fears live, and taboos are the things that keep us tiny. Particularly for women.

If you read all your history books, there are no women in them.

I always give three pieces of advice to all the teenage girls when I do my talks: long country walks - it's important to get some fresh air in your lungs, and be in contact with your body; masturbation - it takes the edge off, it'll get you through; and the revolution - believing in changing the world.

But nearly every woman I know has a roughly similar story - in fact, dozens of them: stories about being obsessed with a celebrity, work colleague or someone they vaguely knew for years; living in a parallel world in their head; conjuring up endless plots and scenarios for this thing that never actually happened.

A library in the middle of a community is a cross between an emergency exit, a life raft and a festival.

I know people go on about Twitter, but it is amazing. It's whatever you want it to be, and all the women got in there before the boys.

So this is why I can't agree with "don't feed the trolls." When millionaire celebrity broadcasters and entire publications start trolling, ignoring them isn't really an option anymore. They are gradually making trolling normative. We have to start feeding the trolls: feeding them with achingly polite emails and comments, reminding them of how billions of people prefer to communicate with each other, every day, in the most unregulated arena of all: courteously.
