Social Bookmarking/Marketing

2 questions:

1) How many of you realize sales from social networking sites like myspace, delicious, digg, facebook, etc?

and 2) I'm trying to adda link on our homepage that allows a visitor to bookmark our page in delicious. I can't find any script. I'm not finished searching yet, but maybe someone here knows? We're on OsCommerce, and the script I assume would be either php or html, as that is mainly what we're using right now.

There is not much of coding for it. Please click on the link above for del.io.us and diggs and see the URLs in your browser and you will understand it. For del.io.us you need to generate URLs like del.io.us/post?url=your url here. And for diggs, diggs.com/submit?url=your url here . You can dynamically generate URLs in language whether php or asp.

Well you can find these links or scripts at del.io.us and digg it self. Check help section
