How to Add an RSS Feed on Blogger?

Step1
Log into your Blogger.com account. This will take you to your Blogger Dashboard, which is a list of all of your blogs on the site along with controls for customizing them.
Step2
Select "Layout" for your desired blog. The "Layout" tab will be displayed, providing a graphical representation of your blog, including the area where blog posts appear and areas where you can add customized elements.
Step3
Click on "Add a Page Element." Another window will open with a list of elements that you can add to your blog. Select "Add to Blog" underneath the "Feed" element, which opens a "Configure Feed" dialog box.
Step4
Copy the RSS link URL from the external blog. Most blogs place their RSS link as either text or an RSS icon somewhere on their blog. Clicking on this link will open a Web browser page with the feed URL, often a Feedburner.com address. Select this link and copy it to the clipboard.
Step5
Paste the RSS link URL into the "Feed URL" box of the Blogger "Configure Feed" dialog. Select "Continue." If you make a mistake, click "Cancel" and start again.
Step6
Save your changes. After clicking on "Continue," a dialog box will open showing the title of the blog feed you are publishing, an option to select how many items you wish to display, and check boxes to show "Item dates" and "Item sources/authors." Make your selections, review how the feed will look on your blog, and select "Save Changes" when satisfied.
Step7
Place your new feed. The feed you just added will show up as the top item in your list of side page elements. Left-click, hold, and drag the feed element to move it to a different slot on the side, or to the top or bottom section of your blog. When satisfied, click on "Save." Then click "Preview" to see how your new feed appears. Use "Clear Edits" to undo the changes and start over.

Add Gadgets to blogger

Google have added some fun new functionality to Blogger in Draft: Google Gadgets for your blog. This feature lets you add pretty much any Google Gadget to your blog’s sidebar.
The Gadget directory is the same one used on iGoogle, which means there are thousands of Gadgets available for you to try. (Note: since most Google Gadgets were designed for iGoogle, they won’t all make sense for display on a blog.)
The Gadget directory is available directly in Blogger Layouts, in the Template Page Elements Add a Page Element popup:

This is an early version of our integration with Google Gadgets, so there will likely be some rough edges.
