I use Flipboard for my news and RSS feeds, but really hate how Flipboard forces every feed you add into separate "magazines." I like all of my news in one magazine, all my tech news in another, etc. Fed up with it, I whipped up a Django-based app that lets me create collections of feeds and then outputs them into single RSS feeds in a Flipboard-friendly format. I can add and remove feeds in a collection from a simple web interface and see the results in my Flipboard app. It's not one of my most amazing creations, but it scratches a really big annoying itch and works great.
