An interesting new site has popped up. The site is whos4you.com and it's a mini article site.
What you find at whos4you is a list of articles on a variety of topics and within the article, you'll find a link to a page that is related to the topic.
If I were the type to bet, I'd imagine this kind of site will become very popular to webmasters and SEO specialists.
If the subject you're looking for is not on the page, the webmaster offers a request page you can request that an article be written and offer a link to a site that is relevant.
This is good SEO for the person "who is" because they end up with a relevent link.
I have a feeling there will be more and more of these types of sites. The articles are short and factual and also make good research material.
As a bonus, the articles can be used in other sites on the condition that the links are kept intact.
