Social bookmarking has been around for several years, and it is finally beginning to gain in popularity because it is a powerful way to organize and share information. Harvey Raybould from OfficialWire.com gives an overview of the use of social bookmarking systems in business promotion.
Marketing research firm Nielsen has some stats on the habits of UK social networking users, and it once again shows that social networks, for the most part, adhere to the Pareto principle (also known as the 80/20 rule).

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.
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.
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.
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.
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.
