A bit of quitlit from Stephen Fry on why he is leaving Twitter:
To leave that metaphor, let us grieve at what twitter has become. A stalking ground for the sanctimoniously self-righteous who love to second-guess, to leap to conclusions and be offended – worse, to be offended on behalf of others they do not even know. It’s as nasty and unwholesome a characteristic as can be imagined. It doesn’t matter whether they think they’re defending women, men, transgender people, Muslims, humanists … the ghastliness is absolutely the same. It makes sensible people want to take an absolutely opposite point of view. I’ve heard people shriek their secularism in such a way as to make me want instantly to become an evangelical Christian.
But Stephen, these foul people are a minority! Indeed they are. But I would contend that just one turd in a reservoir is enough to persuade one not to drink from it. 99.9% of the water may be excrement free, but that doesn’t help. With Twitter, for me at least, the tipping point has been reached and the pollution of the service is now just too much. (Source)
