Variety is the spice of life.
If librarians spend all day constructing web sites and writing handouts, they will develop an insularity that cuts them off from live patrons. We need the refreshing slap in the face of patrons who, on the phone or in person, ask us a suprising range of questions. Such primary data will always inform us as we improve web sites, handouts, and collections. Patrons pay our salary. If they don't see us performing for them, they will take us for granted and replace us with nameless computer nerds.
