I came across this tool today. Looks like something very useful for curating content!
The summary below was created courtesy of the Clipped bookmarklet!
“Clipped analyzes text grammatically to extract the most important information from an article. The algorithm identifies sentence structures statistically, and graphically determines predicate-subject relationships to generate the best bullet-point summaries possible. Plus, Clipped re-reads all of its own summaries to make sure they make sense.”
