The document discusses how Flickr can be used to drive traffic to blogs. Flickr has evolved from just a photo sharing platform to something that can effectively market websites, products, and services. People can comment on photos on Flickr, link back to related blog posts, and drive referral traffic. If a photo used on a blog appears on the front page of Digg, it can result in a surge of temporary traffic but also more long-term traffic from new RSS subscribers. Overall, Flickr provides opportunities to enhance blogs with quality photos and generate traffic through comments and links.
