Seems like a lot of misinformation and confusion out there on how to import and display your feeds on Facebook. Here is what worked for me:
1. In the lower left-hand corner of your Facebook account, click on “Applications” > “Notes”.
2. In the upper mid-right column, click on “Import a blog” in the “Notes Settings” panel.
3. In the “Import an External Blog” panel, enter your feed URL and check the little box.
4. Click the “Start importing” button and then click on “Confirm Import” on the preview page.
That’s all there is to it. Don’t forget to edit your “Notes Privacy” settings to ensure that people can see and comment on your imported feed items.
Once you successfully import your feed(s), they will appear by clicking on the “Notes” button in the left sidebar of your Home page. Also, your timeline or “Wall” will also display the most recent post from each of your feeds as they are published and pulled into Facebook. This makes it easy for your “Friends” to see what you have been up to elsewhere on the Web.
