I tend to disagree, an "intelligent news aggregator" adds value to a story (by bringing in more sources) and increases circulation for the source. If you construct your RSS properly you can utilize splogs, and aggregators to expand your reach.

I don't think that this site is going to "increase circulation for the source".

If you look at it, it is far from obvious that the content is being aggregated from other sources. Looking at the front page one might easily assume that this is all the sites own content.

There are no mentions of sources or links to sources on the frontpage. When you click on a link, you are not brought to the source, but instead to another page on the site which republishes the content from the source in full. Again it looks like this is the sites own content.

If you scroll down below the fold you eventually find a link to source but on the articles I checked this just links the the source sites main page and not to the individual article at the source site.

The links to the source are provided as is in the press releases (see my other comment) - I think they do this to boost Pagerank of their main site, not just the article.

You misunderstand how the site works. I'm not republishing RSS feeds of any of the source on the site. The articles come from copyright-free press releases related to the news published by other sites (sometimes, their content is the copy-pasted press release, too, so that might have confused you).

Example of a RSS feed item : http://esciencenews.com/sources/science.daily/2008/05/24/fin...

Link to the source, no full content. The full content articles come from related press releases on universities websites, etc

Unless the source explicitly made those articles public domain (or they're older than Mickey Mouse), those articles are copyrighted. (No, the absence of a copyright notice doesn't mean that they're copyright-free.)

You don`t seem to understand the very concept of a press release.
