Oh well, I heard you and you should check what we do. It looks like this:http://www.feedsapi.com will make your life with RSS nicer and should improve your user experience with RSS. Here are some of the things you can do: Turn those shortened rss feeds into full Text rss feeds, curate your feeds with keywords tomonly get what you really care about, curate your feeds with a more complex filter structure using RegEx, get your feeds items to be delivered everywhere in any format (htmk, txt, pdf, word...) and in full lenght ! 50 sites is a lot... And you may not need to read all of those feeds items so curation makes sense in this specific case.
I hope this helps.
