Ernie (Johlum) posted this on the free download thread, but I felt it should also be posted here...Jon Leger has come up with a pretty cool free "summarizer". It takes SE results, spiders the top ranked sites, and returns sentences/paragraphs from those sites that contain you keywords.
It's free, and to be honest, not sure it isn't almost as good as Instant Article Writer Pro.
A possibility is to take the results from Gist Web and post them at mtruk for a rewrite, giving you cheap, fast, high quality content.
Give Gist Web a quick try:
