I have an idea for an extremely simple but useful feature. I want duplicate posts removed. I subscribe to a ton of RSS feeds and feeds that are aggregations of other feeds. This leads to a large amount of duplicate posts. For instance, traceback.org is listed on Planet Python. Any post tagged with Python will show up on the Planet feed. Now lets pretend that you saw one of my Python posts and decided you liked some of my other content. Subscribing to my blog will lead to seeing my Python posts twice. Google can I have this feature? Some friends have informed me of ways to do this on other software, but right now I am liking Google Reader.
