A few months after being acquired by YouTube co-founders Chad Hurley and Steve Chen from Yahoo! (who had put it on the chopping block), Delicious.com has relaunched today. The "social bookmarking" site, which had a strong following in the middle of the last decade before losing steam, has a new look and some new features.

The core of the Delicious experience, collecting interesting links and sharing them with friends, remains the same. "Stacks," the most prominent of the new features, makes it easy for users to group together links around a common theme. Watch a video on Stacks above.
