A new product - as yet unnamed but dubbed 'The Facebook Cap' - is every social networker’s dream. Fitted with 3G, GPS, and a digital camera, the cap keeps all of your friends up-to-date with your location and pictures of what you are doing uploaded to Facebook.com every 3 minutes. A 16 core computer and a web of sensors built into the cap utilize the latest advances in neuroscience to determine which parts of your brain are active. With some training it can tweet what you're thinking about as you're thinking it! Sounds like science fiction? Actually much of the technology already exists. But perhaps even more surprising is that this type of product would likely find a sizable market. A group of social networkers Celent categorizes as "over-sharers" will jump at the chance to share even more data about themselves. They will look to consumer electronics goods to enable this. Look out for Celent’s upcoming reports on social networking and digital marketing to find out more. Happy April Fools day.
