My one experience of running in Brighton, the Brighton half a few years ago, was not a good one, for a couple of reasons. One cancelled train meant getting there was a seriously fraught experience on a very crowded train that got me there uncomfortably close to the start time, even from as near as SW London. Second, it was the year that they put a cone in the wrong place and made the course at least a quarter mile too long, to a great many brickbats!
I suppose she's the national equivalent of a certain person on here(or banned on here) Her comments (Kate H) are no more valid than any other idiot but thousands of people comment on it. Hundreds comment on the comments. It's trolls, feeding the trolls feeding the trolls(hate to use that term). I'm all for social media but it can reveal the nation for who they(we) are. Usually it's very ugly. Best to keep out of it. You can't win an argument on facebook/twitter.
I think, however, people say things online, even without anonymity, that they'd never say face to face. Ms Hopkins might be one of the ones who would astound you by saying what she says online out in the 'real' world, but as a way of assessing what people really think – well, do Twitter or Facebook do that? Facebook is a sea of 'I'm here, look at me' pictures and 'Today is the first day of the rest of your life' pretend inspirational bullshit. Twitter - to be honest, I"m not sure what it is except vainglory and preening.
