If you currently import content to your Facebook profile’s Notes app from outside sources via a RSS feed, that will change. Facebook has announced the following “Changes to How You Share Content in Notes”:
You currently automatically import content from your website or blog into your Facebook notes. Starting November 22nd, this feature will no longer be available, although you’ll still be able to write individual notes. The best way to share content from your website is to post links on your Wall. Learn more about notes.
This is another way Facebook is trying to have its users share links the same way they do so on Twitter and on Google Plus. If you were previously importing blog posts to Facebook Notes through a RSS feed, you can use an application like Networked Blogs to automatically post your blog post links to your Facebook page.
