As the start of Socail Bookmarking and Networking for Customer Street I have now set up a useful page on Delicious.
The age of social book marking and networking is coming and moving forward on both design and seo everyone needs to be paying attention to this.
The easiest way is to have a blog or other article driven section either built in to your website or on a seperate domain name to assist with your link popularity too.
Mor will be added shortly on social booking.
