As the cofounder of trunk.ly and a direct competitor to delicious, I think this new version is one step forward, two steps back. Social bookmarking is one of the few much under-appreciated services. It offers much longer life-time-value to its users. There are lots of data one can mine. Many needs to satisfy. Chad and Chen's entry definitely revitalize this market. Their "bringing social bookmarking to consumers" is spot on. This is a huge step forward. Over time, I'm sure the service will become better as long as they keep improving it. Two steps back: 1) The main way to get links into delicious is still via bookmarklet. Given the high ratio of people using facebook, twitter, why should I manually bookmark a link if I have already retweeted it? Or liked it in my little walled garden? Trunk.ly provides 10+ connectors into popular social networks. Setup once. Links will start coming in automatically. 2) Lack of a solid social search. Playlist for the web is a great concept but will your interior "design" tag means the same to my software "design" tag? Tagging as a device to build taxonomy starts to collapse when people uses same tag for difference things. Quora solves this problem quite well by labouring out a taxonomy of its own. Trunk.ly provides a search interface so essentially you have your own google for your links as well as your friends. For example, want to search for stunning infrared photography images? This is what you get from trunk.ly: http://trunk.ly/?q=infrared+photography http://trunk.ly/?q=infrared+photography This is from delicious: http://delicious.com/search?p=infrared+photography http://delicious.com/search?p=infrared+photography
