Here is a simple guide to adding an RSS Feed on your personalized iGoogle Homepage.
If you are not familiar with iGoogle, I suggest you have a look first at the following links:
iGoogle – Wikipedia
iGoogle – Google’s Help
For this example we are going to use the “Decoding the Web” RSS Feed.
Step 1:
Log-in iGoogle.
Step 2:
Click on “Add stuff”. (screenshot)
Step 3:
Click on “Add by URL”. (screenshot)
Step 4:
Insert the RSS Feed URL, (for example: http://decoding.wordpress.com/feed/).
Click on “Add”. (screenshot)
Step 5:
Return to the iGoogle Homepage, you should now be able to see the new Gadget.
Click on the top-right small arrow, and then on “Edit settings”.
Select how many items you want it to display, and “Save”. (screenshot)
That’s it, enjoy!

any idea how to see more than 9 items?
