Marjan Herbert of Logica CMG took us on a journey through the Web 1.0 of the past, via the present Web 2.0, to a possible future Web 3.0 and even Web 4.0. We all remember static websites 1.0. Brochure-like expositions of companies on the web, on which you could only take information and do little else. With Web 2.0, this has changed. We can not only read, but also write, on our blogs or microblogs (e.g.Twitter), on our social network profile (e.g. Hyves, Facebook), we can put our pictures online (e.g. Flickr) and tag them by putting a label on them that’s meaningful to us, like we can also do with other content we find online (e.g. del.icio.us) and based on these meta-data, these tags of millions of people, aggregators can tell us which content is best-rated or most viewed or whatever. This is a big difference with the static “take it or leave it” websites of the past. Now we can create content and enhance/augment it by placing our own stamp on it. These are the first steps that bring us into the era of Web 3.0 according to Herbert, because based on the tagging that people do, one can analyze data based on their mutual relevance which gives information on the context of the information.
