Blogs and Wiki's   Technically a Blog is just a cut-down web posting form or discussion forum where only one person is allowed to post a "subject" and "article". Other posters may comment on the article originally posted but they cannot do so in a position of equality (the original "article" always has the place of prominence). A lot of blogs have formed into communities of bloggers so many people can post articles and others can comment on the articles... but only in a format where the original always maintains a place of prominence. Blogs are a new innovation on an old theme.   Positives -   Blogs encourage participation  Blogs are very easy to use Blogs foster opinionated commentary (is this really a positive?) Blogs support various means of interlinking content with other Blogs and articles Blogs are unmoderated   Negatives -   Blogs typify a culture of individualism (is this really a negative?) Blogs are not truly democratic (the original post always has a place of prominence above other comments or feedback) Blogs tend not to foster open discussion (when compared to a Discussion forum)   To me a Blog is nothing new; a buzzword - but the concept of encouraging people to "Blogg" raw opinions and ideas in a format archived for posterity is new. Maybe an old tool working for a new world?   On the other hand a Wiki is something completely different and IMO embellishes the concept of "something new"... Technically a Wiki is the same as a Blog, but with one vital difference - Wiki's encourage collaboration and directly challenge the concept that "anything written is something owned". Anyone can edit a Wiki; anyone can change the original content meaning a Wiki is truly a living document. Somthing new for a new millenium in a wold dominated by copyright.
