Many blogs seem to suffer from a certain ennui from time to time, a sense of futility, of howling into the void. Al Jahom recently wondered why anyone bothered to refute George Monbiot's column on house-sharing, taking it to be 'outright trolling'.
I can't speak for everyone, but I can only say why I do it - because if no-one does it, then we have allowed the gradual (and carefully planned) softening up of ideas, as another commenter to that post puts it.
And as Anna Raccoon points out, the world of blogging may be changing, but it's changing for the better:
"The pace of life in the Blogosphere has changed. The house seems more serene; peaceful even – and purposeful.
I would venture to suggest that Bloggers have grown up; the truculent adolescents with their monosyllabic chant of ‘shan’t’, ‘won’t’, ‘don’t like it’ have left home, off to wave banners and utter two word comments on Twitter.
In their place is a new breed of Blogger. More thoughtful, less prone to knee jerk reactions, with a dedicated purpose to their prose – that of enlightenment in some corner of life that the main stream media are unable/unwilling to cover in any meaningful depth."
