I've added some more links to the 'navigation bar'. These reflect some changes in the topics/categories section.
I've made these changes because I've realised that visitors to the blog come for many different reasons and often arrive on pages that are no longer displayed on the 'home page'.
In some respects I am essentially giving up on the notion of a 'home page'. In future stories are quite likely to be published first in the category sections of the site. They will be linked to directly by twitter at the point when they are published.
