Facebook founder Mark Zuckerberg told a live audience yesterday that if he were to create Facebook again today, user information would by default be public, not private as it was for years until the company changed dramatically in December.
Tim O'Reilly attempts to clarify just what is meant by Web 2.0, the term first coined at a conference brainstorming session between O'Reilly Media and MediaLive International, which also spawned the Web 2.0 Conference.

Denise Pires, a student from University of Amsterdam, wrote in the blog "Masters of Media" about why we, as human beings, tend to use the well-known microblogging service.
In this post from the blog "The Innovation Diaries", the author tries to categorize people's tweets into a hierarchy resembling Abraham Maslow's Hierarchy of Needs for human beings. Each category is well explained and then illustrated by a few examples.
In this talk, Jonathan Zittrain made proposes that the seemingly lost human kindness has blossomed on the internet. The talk starts with the basic infrastructure of the internet, all the way to the simple but brilliant ideas of information sharing, to explain the act of kindness of human. This differs from ratings on amazon in that it is proactive and conscious actions of internet users who give and pass on favors.
In an effort to add one more story to the list of reasons why Facebook already rules the world and can stop trying, we find that Facebook is the social-network-login of choice by nearly 2-to-1.
Navigation is a daily part of our lives any more. Several vehicles are made with GPS built in, and most of the rest of us have a GPS device of some sort. When it comes to getting where we need to be with out getting lost, well, we are pretty much …
Big changes are coming to Facebook Platform. Today, Facebook is granting developers on Platform the ability to request (or require) users to hand over their e-mail ids..
In December, Facebook made a series of bold and controversial changes regarding the nature of its users' privacy on the social networking site. The company once known for protecting privacy to the point of exclusivity (it began its days as a network for college kids only - no one else even had access), now seemingly wants to compete with more open social networks like the microblogging media darling Twitter.
TED Talks: While news from Iran streams to the world, Clay Shirky shows how Facebook, Twitter and TXTs help citizens in repressive regimes to report on real news, bypassing censors (however briefly). The end of top-down control of news is changing the nature of politics.
As collaborative or team-based projects become more popular in both secondary and post-secondary classrooms, instructors are looking for ways for group mem bers to effectively evaluate one another. Constructing effective evaluation tools can be a daunting task. As shown by a review of literature, best practices include (1) building a foundation in the classroom that supports collaborative evaluation, (2) creating effective evaluation tools by articulating specific criteria and ensuring honest student participation (3) implementing formative feedback during the col laborative experience, (4) formulating summative feedback at the conclusion of the experience, and (5) assessing the collaborative evaluation process.
his article describes and evaluates several peer evaluation tools used to assess student behavior in small groups. The two most common methods of peer assessment found in the literature are rating scales and single score methods. Three peer evaluation instruments, two using a rating scale and one using a single score method, are tested in several management courses to examine their effectiveness. All three instruments demonstrate acceptable levels of reliability and are found to be correlated with individual performance measures. The article concludes with a discussion of the advantages and disadvantages of each instrument.
Providing fair assessment with timely feedback for students is a difficult task with science laboratory classes containing large numbers of students. Such classes are usually assessed by short-answer questions (SAQs) centred on principles encountered in the laboratory. It has been shown recently that computer-assisted assessment (CAA) has several advantages and is well received by students. However, student evaluation has shown that this system does not provide suitable feedback. Thus, the authors introduced peer assessment (PA) as a complementary procedure. In October 2006, 457 students registered for a first-year practical unit in the Faculty of Life Sciences, University of Manchester. This unit consists of ten compulsory biology practical classes. The first four practicals were assessed using PA; the remaining six practicals were assessed by CAA and marked by staff or postgraduate student demonstrators. The reliability and validity of PA were determined by comparing duplicate scripts and by staff moderation of selected scripts. Student opinions were sought via questionnaires.
The authors show that both assessments are valid, reliable, easy to administer and are accepted by students. PA increases direct feedback to students, although the initial concerns of student groups such as mature and EU/International students need to be addressed using pre-PA training.
Without much surprise there has been significant movement within some of the social networks over the course of the last year. Brian Chappell from Ignite Social Media has put together a comprehensive report based on data from all major social networks existing on the web.
Ohloh is a free public directory of open source software and people.
Ohloh is a wiki, and anyone is welcome to join our community and add new projects to our directory, or to make corrections to existing directory pages. This public review makes Ohloh one of the largest, most accurate, and up-to-date software directories available.
Ohloh is not a forge -- we do not host open source projects in the traditional sense. Ohloh is a directory, a community, and an analytics service. We use the data from our directory to create historical reports about the changing demographics of the open source world.
Our goal is to develop a probabilistic knowledge base that mirrors the content of the web. We are developing a system that uses semi-supervised learning methods to learn to extract symbolic knowledge from unstructured text and HTML. We are exploring methods of continous learning, where our system runs 24x7, continuously learning to read better, and continuously extracting facts from the web.
The power of collaborative effort, especially relevant to us Pittsburghers. People can report on the road and snow conditions on streets close to where they live.
