I saw the word plog on /. today and felt compelled to investigate. I followed the links to this article about the plogging phenomenon. In shrot, a "plog" is geekspeak for "project log," which works rather like a blog--but for IT professionals.

The article discusses the advantages and disadvantages of plogging for IT companies. On the one hand, the "internal" info that can be generated by plogging is extremely valuable for management and employees. On the other hand, information leakage could potentially damage company, especially if junk traders can peer into a corporation's innards.

Apparently, several companies are looking into the potential of commercial blogging.
