Digg CEO Jay Adelson has announced he is stepping down from the position to pursue some entrepreneurial concepts of his own. He's served for five years, and will be replaced in the interim, by Digg Founder Kevin Rose.

"With the new Digg getting ready to launch, Digg Ads doing well, our sales force growing, our hiring ramping, and the company maturing well beyond its startup phase, I feel that now is the right time," Adelson said in a statement.

"The entrepreneurial calling is strong, and I am ready to incubate some new business ideas over the next twelve months," he added. "As the economy exits a very deep recession, I believe that it is an excellent time for new companies to develop."

Rose offered a statement of his own. "While I'll miss working with Jay day-to-day I am excited to be taking on the role of Chairman and acting CEO, driving Digg forward on our promise to enable social curation of the world's content and the conversation around it. We've been super busy on the product side getting ready for the upcoming Digg redesign and delivering our mobile apps for the iPhone and Android." More about these here and here.

Adelson will continue to served as an adviser to Digg.  The company is not offering any more details beyond what's in the announcement at this point.
