People use the Web for different purposes; among others, getting connected by online communities and sharing information is one of them. According to the lecture, the term Web 2.0 is used to describe any technology that allows web users to create and share information, as well as, to collaborate easily with each other. There are a lot of different technologies offered by Web 2.0. The following paragraphs will introduce you to the most important types of Web 2.0 technologies: Blogs, Forums, Social networks and Wikis.
A Blog is a journal that is often authored by one person and sometimes teams. The blogger is in control of the discussion, but the audience can leave comments or questions. Mostly the blogger publishes thoughts about what he/she has experienced or learned. Usually, such blog posts are relatively short, but have enough information in it to engage the audience. There is a special form of blogging, called Micro blogging, like Twitter, where the posts are much smaller and differ in their content.
A Forum is different from a blog in that way that everyone is at an equal level, i.e. there is not only one author/author-team, but each participant can add some content or even a new topic. Usually forums are organized by topics. A special form of a forum is the Discussion forum, one like the ISM course page provides, where students can ask other students for help. It is not possible to change the edited posts of one student, but you can reply to each post, if you, for instance, know the answer to another student’s question.
A Wiki is a web page that can be edited by many people (e.g. Wikipedia). Characteristic for each wiki is the attitude that it is open and based on collaboration. Most Wikis use special software, but you can also go to webpages like, www.wikispaces.com, and create a basic plan wiki, for free. In general, if you see a wiki post, which is to your option wrong or can be improved, you can edit it. Most times, editing rights are limited with regard to edit, change or remove material.
A Social Network allows its members to organize around a person’s relationships or interests, rather than just focused on topics (e.g. Facebook). People in a social network are connected by a common interest and share personal information with the people they already know or those they want to meet.
