This last week I discovered www.problogger.net, a site that ranks in the Technorati 100. For those of you who don't know, Techorati is a website that ranks blogs.
Problogger has a terrific post on how to pick a profitable blog topic, and I think the logic holds true for Yepic as well, with maybe a few slight alterations. For starters, Yepic's first authors will have to provide content that exceeds the standards of blog content, particularly in terms of specificity and expertise. Before you write a Yepic post and try to sell it, make sure you surf the bloggosphere looking for comparable data.
ProBlogger also had this article on how blogs make money online. I was happy to see him mention "digital assets," which he identified as eBooks, tele-conferences, etc. It's good to see bloggers recognizing the demand for deeper treatment of the subjects they discuss on their blogs, and Yepic is a great platform for that type of content distribution.
