the goal of providing users a secure way to access their address books and friends lists without having to take their credentials or scrape their data

OAuth has provided a standard to unify the various proprietary schemes for delegated authorization

we can do the same thing for securely sharing address book and friends list data

The result is an egregious lack of productivity that may cost the U.S. economy $588 billion a year, according to a report by Basex, which has tabbed information overload as the "Problem of the Year" for 2008.

With e-mail as the biggest offender, Basex said users can save time by not e-mailing someone, and then following up with a phone call or an instant message two seconds later

Basex also said users must not combine multiple topics or requests in a single e-mail; make sure the subject clearly reflects the topic and urgency of the message; read their e-mails before sending to make sure they make sense; and will not hit reply-all unless necessary or reply with one-word e-mails such as "thanks.

The most robust definition (and the most commonly cited) seems to be found in Barbara Gray's Collaborating: Finding Common Ground for Multiparty Problems. She describes collaboration as "a process through which parties who see different aspects of a problem can constructively explore their differences and search for solutions that go beyond their own limited vision of what is possible."[5] In Collaborative Leadership, David Chrislip and Carl Larson offer a slightly different but also useful definition: "It is a mutually beneficial relationship between two or more parties who work toward common goals by sharing responsibility, authority, and accountability for achieving results."[6]

What Is Collaboration? Wood and Gray say that each definition of collaboration used in the articles reviewed has at least one important element missing. They say that any definition must be able to answer the following: Who is doing what, with what means, toward what ends? "This leads us to create the following revised definition," they write: Collaboration occurs when a group of autonomous stakeholders of a problem domain engage in an interactive process, using shared rules, norms, and structures, to act or decide on issues related to that domain. Stakeholders may have shared or differing interests in a problem domain, and these interests may change over time. Some degree of autonomy is required, or else stakeholders "merge" rather than "collaborate." Rules for governing interactions must be implicitly or explicity agreed upon. Acting or deciding is needed to reach a common objective. The domain is the issue or set of issues that stakeholders are interested in, such as local traffic congestion or a nation's economic health. Wood and Gray say that this definition is general enough to include a wide array of collaborative forms but specific enough to exclude others, such as blue ribbon panels that never meet, corporate mergers, and clubs that have no specific problem-solving objectives. The authors next discuss the other 3 issues confronting a comprehensive theory of collaboration.

The current release of Chandler builds upon the experimentally usable calendar for individuals and small workgroups. It is a test release for collecting feedback based on real usage. In addition to basic calendaring, advanced features include: recurring events; time-zones; overlayed, multiple calendars; and managing a single event across calendars. Chandler offers innovative capabilities in calendar sharing to support workgroup collaboration. Chandler sharing is server-based, works across platforms and supports multi-author editing. Our goal for our most recent release, 0.7alpha4, is to give a rough sketch of what Chandler will be by our first Preview release (Spring 2007). This release introduces the Dashboard, which gives users a runway view of all of their information. Users can try creating a simple task list, and can share that list with others just as they can share calendars. Users can also experiment with sending notes, tasks and invitations to others via email.
