StumbleUpon: You never know the next website | YouLi Link™

This is a random URL recommendation website which is rather famous abroad. Based on its own algorithm, as long as you want, there are good websites for your continuous browsing by just clicking next. This kind of randomness but not completely random way of playing is not a bad choice to kill the boring time. Currently at home Ken Yiken which is gradually becoming popular is also a similar random recommendation website. It's very interesting.
