Want to add a cool technology component to any group or class project? Try blogging! Hosting is free from a number of sites. Two popular sites (rivals) are Windows Live Spaces and BlogSpot. The interfaces are simple to use and support a wide variety of looks, and allow the posting of text, photographs and video.
Both Windows Live Spaces and BlogSpot can be configured to make the sites non-searchable, or members only, and comments (desirable) can be moderated to prevent spam posting. Of course students should be strongly cautioned to not post any personally-identifying information on their blogs, particularly K-12 students. Following are a collection of student project blogs from a game development class at Cal Poly Pomona. The quality of the blogs and the projects vary greatly, but they give a good idea of how students can get their work out there without spending a lot of time on web development.
