FeedKiller is an online tool for merging RSS feeds. With FeedKiller you can combine multiple feeds into one universal feed. The idea is nothing new, other tools that can be used for that purpose are RSS Mixer, Feedoor and FeedBlendr. However what makes FeedKiller standout is the ability to select the number of stories to include from each feed. For instance, frequently updated feeds can be set to include more items than the ones with lower update frequency.

    I hope you can help me since I already browsed through the rss tag of MUO, but could not find something fitting, but I think, it must exist?
    I am looking for an online app, that would allow me to monitor for example 2 blogs, that has nearly the same content, but well, not 100% the same.
    like 80% of all posts are identical, and only 20% are different in each blog.
    is there a way to merge those two blogs, and have a feed that is returning to my feedreader the content, but excluding the double content?

    I would be so grateful if you could help!
