With social news site Digg set to launch a radically-revamped site - new. digg. com - the company’s chief executive Jay Adelson Sunday elaborated the site’s changes to the attendees at the South by Southwest (SXSW) conference in Austin, Texas.

Adelson specified that key changes that the new. digg. com site – which has been under development for five years and will go public in the coming weeks – will undergo include a much enhanced performance and customized personalized homepages; thereby hinting at Digg’s prospective competition with Twitter and Facebook.

The new. digg. com site is presently involved in the process of collecting email addresses of potential users who would be sent out a notification when the new site has been prepped up for user testing.

According to the information revealed by Adelson, the new Digg will boast the capability of handling millions of submissions every day. The revamped site will virtually cater not only to the growth in Internet audience, but also to the automated submissions that are made via Internet APIs – whereby computer-powered systems can submit one thousand URLs to Digg, in time taken for one manual submission.

The 2004-founded Digg, which is leaving no stone unturned for ensuring the user acceptability of the revamped site, is collaborating with social media news site Mashable, to test the new site’s overhauled Digg buttons that help users submit or vote on Internet links.
