When you are first beginning to blog it helps to become familiar with the different vocabulary related  a blog like blog titles, articles/posts, sidebars, links, permalinks, comments, archives, blogrolls, and other terms. This SlideShare show will help you see where these different parts are located.

The first thing I look for on a blog is an "About" link or a place that tells me about the author of the blog. I want to know who is writing the information and other information. I like to know if they are classroom teachers or what their job is. It helps me understand their perspectives. If I can't find it easily sometimes I navigate back to the very first post. Sometimes authors will introduce themselves there. You will see archive links on many blogs
