I'm looking for a news/content solution for an industry site I'm building that will provide news as it happens on to my site. There are a wide number of niches within this industry that I would like to cover. From a look around alot of the websites I will be competing against use feeds which some appear to be re written and others straight copied from source site. There are a wide amount of options to use including aggregating different feeds into one feed then reading this on my site, to paid for solutions which scrape the web and rewrite the content they provide. What do the acorndomainers use and who would you recommend? Do you feel the services which rewrite content are worth it for the seo advantage, or does this depending on the source permission enter the grey territory of plagerism?
