You see my site is a software site and since its relativebly new I get most of the programs defenition from cnet or softpedia, now is this also seem by google as duplicate content. If so a lot of sites will loose their pages in google too since all software have only one way to define them :)
I think this will definitely be seen as duplicate content. The appearance of scraper sites not helping your cause. You probably would have been fine doing this 2 years ago.
