You can share an iGoogle tab that you have created, including its gadgets. Click on the little arrow next to the tab name and select “share this tab”. Then enter the email addresses of the people with whom you want to share the tab, a short message (optional), and send it off. Each person in your list will receive an email with a URL that triggers a confirmation dialog. This allows the recipient to choose which gadgets in the tab are to be added to their own iGoogle home page.
You can view your Google Reader RSS feeds on your personalized iGoogle home page. Sign in to your iGoogle page, click on ‘Add stuff’ and then search for Google Reader. Click on the ‘Add it now’ button next to the details for the ‘gadget’ and it will be added to your home page.
