Barry Norton writes "The Guardian has quite an insightful article about recent Yahoo acquisitions Delicious and Flickr. They quote Joshua Schachter, Delicious' creator: 'We're excited to be working with the Yahoo search team - they definitely get social systems and their potential to change the web. We're also excited to be joining our fraternal twin, Flickr!' And why Yahoo's interest? The article opines: 'It takes a lot of the hard work out of searching the web. The very clever thing about social software is that it puts the burden on to the user, not the provider.'"
