I’ve noticed more and more blogs using the Sociable plugin lately and so I installed it myself. As the internet and browsing seems to be moving more and more towards “social browsing” I think it’s a great extension to have.
Basically the sociable plugin allows you to append your posts (as well as pages, archives, searches and single-pages) with selected links to social browsing sites. You can easily submit a post to sites like Digg, Fark, del.icio.us and many more. If you’d like to add this to your blog simply grab the sociable plugin. It’s really easy to install.
