Recently I had the opportunity to use a Plantronics M3000 Bluetooth headset for several months. My normal headset is a Jabra FreeSpeak BT200. The Jabra is easy to use, extremely comfortable, and produces high-quality sound through both the speaker and the microphone. The Plantronics doesn't match any of these.
Blogs can be a great form of viral marketing. Why? The functions in web logs that separate them from a bulletin board or discussion forum and allow blogs to intermesh. Specifically, I'm referring to TrackBacks and Pingbacks. What are these functions, how do they work, and why do they allow blogs to be non-intrusive viral marketing tools?
