What You Can Find in a Blog Sidebar
Some blogs don’t have sidebars at all, and on other blogs, you may discover additional elements beyond what you see listed here.
Date-based archives: Nearly every blog is archived as it’s published, by date and by category. In the sidebar of a blog, you can usually access both archive methods.
Categorized archives: By sorting each post into a category at the time it is published, a blog can create an archive organized by subject, making it easy for you to find the posts you’re most interested in. Clicking a category link displays only the posts in that subject area, in reverse chronological order.
Blogroll: A blogroll is a list of blogs that you find interesting or useful. By including blogs and Web sites the blogger likes to read, you can direct your readers to other interesting Web sites. And who knows? Those sites may return the favor, sending their visitors to your site.
Information about the author: Because blogs are so personal, sometimes you want to know more about who’s writing them. Many bloggers know their readers are curious and put together short bios and other information for readers.
RSS feed link: RSS, or Really Simple Syndication, is a way readers can subscribe to your blog by using a newsreader, such as Google Reader. After a reader subscribes via RSS, she can read the latest updates via the newsreader rather than visiting your blog. This is helpful because it means your readers don’t have to visit your blog several times a day to see whether you’ve updated it.
