Blogging Resumes

What if we used blogging as a portfolio for our employers? It seems useful, accessible, and an efficient easy-to-use tool to show employers a daily representation of one's work. I understand that some people feel as if their work would be publicized and wish to keep private ownership or credit but in those cases we should create private blogs. Medical Journals for example now exist on a database that is only accessible by researchers, students, and other authorities with clearance. If we researchers could blog updates about their approach to a problem then there could be a worldwide collaboration between researchers to solve a problem. Although blogs are somewhat of a nuisance in certain cases where it is used to post daily updates of one's social life which seems irrelevant to an employer, I feel this negative is out-weighed by the impact of a social collaboration on research, innovation, and networking.
