Rachel from North London was one of the people who was caught up in the London bombings last summer. Her blog digs around a lot of the issues - those of forgiveness and attempting to understand what happened - why it happened, and reflections on the 'victimhood'.
She posted a on December the 14th supporting calls for a public enquiry about 7th July bombings. I've disagreed with her in the comments thread if you're interested. But, among her many posts (and I think she is one of the most prolific bloggers I've come across for a while), she links to a piece about blogging as therapy.
"About one-half of bloggers (48.7%) keep a blog because it serves as a form of therapy, and 40.8% say it helps them keep in touch with family and friends. Just 16.2% say they are interested in journalism, and 7.5% want to expose political information. Few see blogging as their ticket to fame."
I'm surprised no-one answered that, if they didn't blog, they'd probably go out and throttle some one who has a deep-seated need to be throttled.
