One of the most wonderful things about social bookmarking research is,
well, how very social it is. We congregate around our systems like the
way people used to gather around water coolers. I love the way that
the first impression I get from a page is not of link counts or tags,
but of people with varied interests, and I want to improve support for
collaboration in order to bring people out even more.

Another remarkable thing about social bookmarking is that people into
it _love_ sharing information. They share bookmarks, bibliographies –
heck, even blogs. I can browse around a social bookmarking site and
get a sense not only of what I need to know about the system itself
but also the other hobbies and interests of the early adopters.

It's an amazing field to get into, and very very exciting.
