Delicious in a sole-person library

I can see the potential for Delicious, the social network website organiser, for my work in the library. I could use Delicious to organise websites and make them searchable with tags. Most of my work involves searching on the internet for information. I work in a sole-person library, supporting 60 or so professional staff who have interests unrelated to the acquisition of information. My bookmarks would be of interest to nobody but me. At this stage, I can't see my bookmarks being useful to others at my workplace. That is, the social networking function of Delicious would be little use to me.
