Del.icio.us finally adding a feature

After months of stagnant development, the Yahoo Search Blog announced a new del.icio.us feature that makes it easier for people to connect and share bookmarks. Sort of. The feature is named Network Badges, they basically shows others "your user name on del.icio.us with a link to your bookmarks, how many people you have in your network, how many fans you have, as well as a link others can use to easily add you to their own del.icio.us networks."
My question is, if the whole idea behind social networking is to connect with friends to enhance your experience by getting connected with people you like, why would someone want to post a badge on a website so random people can connect?
