Blogjects = objects that blog
"The three major characteristics of a blogject are its sense of space combined with its ability to track where it has been, its knowledge of its encounters and previous experiences, and more importantly, its ability to participate in an assertive way to social networks. "In its most basic form, a blogject is not dissimilar to people that blog -- it is an artifact that can disseminate a record of its experiences to the web."
