The first of a dozen or so sites that Byrne’s C-Change Media is planning to release went live this week: Poets & Quants, positioned as “the go-to place for serious applicants to the best MBA programs in the world.”

The site includes original content, school rankings, and the beginnings of community and social network for MBA applicants and students. C-Change says a niche site for MBA’s is a “a natural starting point for Byrne,” who is the person who created the first regularly published rankings of business schools at BusinessWeek, authored four editions of BusinessWeek’s Guidebook to the Best Business Schools, and built out the brand’s business school franchise on the Web in the mid-1990s.

The next site C-Change plans to launch: “Slingshots for David,” which C-Change says will “provide the tools, advice and inspiration to help entrepreneurs develop disruptive business models to slay the Goliaths in business.” Release date TBA.
