The more observant of readers may have noticed that new bookmarking buttons now appear both on the right-hand sidebar and at the foot of all articles. These allow you to file the contents of this blog on your favourite site (at present, Technorati, del.icio.us, digg, Reddit and NewsVine are supported). See also Wikipedia’s article on the subject.
The buttons to the right will create a bookmark for the entire site. Those appearing at the end of an article will bookmark just that article. As ever if you experience any problems with these links, please tell me about them on the Report Problems page.
Hopefully this minor tweak will make the site more convenient for visitors.
