What if there was a weblog publishing system and web server on a chip? It gets even more interesting if it is combined with low cost geopositioning, low power wireless connectivity, and "controller functionality." Embedded weblogs solve the problem of how to add interactive intelligence to a physical object. If the cost of a system like this was inexpensive enough, you could effectively put a weblog on everything of interest in the physical world. The weblog would record the history of the device: location, controller setting changes, etc. The weblog navigation system on the left or right would provide access to controller settings. Let you imagination go wild thinking about where they might be embedded.
The biggest impediment to embedded computing isn't the cost, its the plethora of proprietary user interfaces. People just won't take the time to learn them. The tablet PC offers a large visual environment to display the interface (as well as an easy to use pen-based input device), the weblog offers the most basic of web site interfaces, RSS offers a way to interconnect or aggregate systems in a human readable way, wireless connectivity provides seamless networking, and the embedded webserver provides remote access/viewing.
Buildingblogs, deviceblogs, sprinkerblogs, heatingblogs, coolingblogs, carblogs, securityblogs, airportgateblogs, TiVoblogs, product trackingblogs, the list goes on (I will leave the snappy names to others).
