I worked on auto-summary-generation in the late 90s (I know I know, lawn, get off you shall) When I ragged on Summly elsewhere ("yet another example of people claiming genius inventions by under-18s that fall short upon closer inspection of the claims") I came across http://skimzee.com in a comment of an older guy who complained about the attention Summly generated.
Skimzee.com lacks the web 3.0 design finesse, and hipp-ly name, but does a very admirable job summarizing articles in various languages. Tried it out and was very impressed, simple interface, works on non-English languages as well. Deserving your attention/feedback.
(disclosure: have nothing to do with the site, but did communicate with the creator a couple of times. very smart older guy.)
