People are looking for a certain type of data on the web.. articles. And they can't find them as easily as they'd hope.
Search indexes and engines aren't really suited to finding - just- articles. They find pages or sites, but the best data unit for professional information on the web is 'articles'.
I'm proposing a site which specifically deals with articles as search objects rather than sites or pages. From my initial market research, something like this which is unbiased and non-commercial could be a major hit. I'm going to continue further with my inquiries and make a prototype.
Of course, all free and any source will be open! I'll post more as I get closer to a result.
