One of my latest and greatest projects involves using Wordpress, the open source blogware, for featuring student work. Wordpress is extremely easy to use and set up, has beautiful templates, and will even host your blog for free if you don't have the resources to get it going. As an excuse to regularly take my class for breakfast, I created a blog called Honolulu Breakfast and Malasada so international students could post their reviews of local breakfast spots in English.
A link was put on the school's homepage, and just like that, a schoolwide blog, open to the public was born discussing breakfast, and who doesn't like breakfast. Wordpress opens up all kinds of possibilities, as does all blogware including Blogger, google's free one.
