Do you think there is any correlation between a site's traffic or ranking based on how many people submit to: http://delicious.com/ ? Like if someone had 10 votes submitted while another has 300 votes...
There are some of us that think Google give some SEO emphisis on sites/content like delicious. But we have compaired sites on this, from a link standpoint, no - from a traffic standpoint, yes - from a ranking standpoint, no. As for "vote" it is still unknown.
