Bishop Hill has a thread on his experiences of being ‘moderated’ out of the discussion (in our terms “rejected”) at what he calls “The Grauniad” – the UK’s Guardian newspaper.
The Guardian has a blog called “Comment is Free”. It appears that they mean that it costs nothing to post there rather than any commitment to fostering free speech.
Rather than preempt the Bishop’s take on this, we will instead direct you to his blog where you can have a look at his post, and comments thereto. http://bishophill.squarespace.com/blog/2010/1/14/guardian-moderates.html
(sorry – you’ll have to cut and paste the address. Still haven’t figured out how to post a link).
