Anatomy of a blog

Let's put Patroclus – patron saint of blogging and the Po ly Styrene of the blogosphere – under the microscope:

• Blogroll– list of links to other blogs in your sidebar.
• Categories – A collection of topic-specific posts
• Comments – enabling readers to leave their remarks
• Navbar – a navigation bar usually seen on top of Blogger-hosted blogs.
• Post, Entry – individual articles that comprise a blog
• Sidebar – One or more columns along one or both sides of most blogs' main pages
• Tags – keywords attached to similar posts
• Trackback – A system that alerts another blogger that you've mentioned their article.
