Nova Spivack, technologist and cofounder of one the first Internet companies (EarthWeb in 1984), spoke earlier in the month at the Future in Review FiRe conference in San Jose, CA.
He made the following observation: "We're moving from a web that was like a refernce library to a web that's increasingly like radio or TV".
Right on. This reflects a move from the Internet being a bunch of pages you surf to a set of self-describing objects that you 'tune into in terms of interest areas'.
This is the world of the semantic web, and will create opportunities for new semantic web apps, such as Nova's own twine.com, which has been described as your own artificially intelligent personal web assistant.
The semantic web technology has been talked about for several years, but the question is when will it become mainstream.
