Surveillance of blogs may not always be the result of high-tech capabilities. Blogs can come to the attention of management through the personal association of colleagues with the blogger. Once the blog is thus brought to the attention of management then a variety of methods might be used to keep watch on the blog.
Importantly blogs can come under retrospective surveillance. Internet archives often reveal the complete contents of a blog despite attempts by the author to delete the blog. As an example a quick Google search can locate the archive of the Washingtonienne; a blog that resulted in the dismissal of its author despite it being deleted prior to the dismissal.
