Downworthy replaces hyberbolic headlines from bombastic viral websites with a slightly more realistic version. "Literally" becomes "figuratively", "Will Blow Your Mind" becomes "Might Perhaps Mildly Entertain You For a Moment", and so on.
In the future we may be able to have all sorts of agents filtering our incoming news.
ETA: Crap, it filtered its own description! Hang on, let me fix that. :)
