One easy way to get unique content is to transcribe audio or video into text.
If you had a service or software that could visit the top video sharing sites, like YouTube or Vimeo, and even audio and podcast sharing sites. The software would crawl these sites for content based on your desired keyword.
It could then instantly convert the audio or video on those sites into text using audio to text conversion.
Since search engines can't read video or text, that would be an instant unique article for you. A bit of additional spinning with The Best Spinner just to be safe..
Apart from creating unique content, such a tool would enable you to quickly and easily create press releases for various topics based on transcribing news report videos from YouTube.
