Anyone who can access the Internet can be part of the knowledge-access, knowledge-building, information-exchanging culture, regardless of location. The research presented in this article is about blogs and their use in a new teacher professional development project. Weblogs were first named and described in 1997 by Jorn Barger (Blood, 2000) and then shortened to blogs by Peter Merholz in 1999. According to well-known New York Times journalist Tom Friedman (2005), blogs and "wikis" or Wikipedia (from the Hawaiian word for "quick"), the online encyclopedias created by intellectual commons collaboration, are two examples of how computer technology is contributing to the "flattening" of the world. Compared to other online discussion tools, blogs are easy to use and involve little cost. This research describes how blogging was used to help launch a science and mathematics teacher professional development project quickly, while more sophisticated but time-consuming portals were being considered.
