I've noticed that when I look at the news feeds in facebook, it doesn't show updates from all of my friends. Is there a way to get an rss feed that contains status updates (and possibly shared links) posted by ALL of my friends? Or do I need to create a separate feed for each friend (not feasible.)
Facebook doesn't offer an RSS feed but you may use a service like NutshellMail to get all the Facebook updates in an email newsletter. Pass this newsletter to FeedMyInbox.com and there you have an RSS feed of all your updates.
facebook limits the number of your friends that get shown in your newsfeed, you need to click the edit options at the bottom of your "most recent" feed page, and edit the number of friends that get shown in your feed.
