Content-sharing site Digg is plagued with controversies and denials these days. Despite its recent discussions with investment bank Allen & Co, Digg CEO Jay Adelson has insisted the company is not for sale anytime soon. Moreover, he turned down the speculations that the company will go public next year.

Adelson also downplayed its rumored acquisition plans for Spanish-language content-sharing site Menéame and another social voting platform coRank, saying they do not have “large cash pool to ‘go and make crazy acquisitions’ with.”

Well, this is not really a denial game for Adelson. He has revealed to BusinessWeek the general direction of Digg in 2008 – international expansion and more new features designed for better customization and personalization.

Some of these new features include alerts for new stories preferred by users, rating system similar to eBay’s, and “story suggest” function which recommends articles similar to what a user has recently read or rated.
