I'm listening to to vidcast by James Rattner on the 3D Web or Internet. (IE on Windows required for full presentation). His SecondLife avatar started his presentation in but started talking seriously in person about the 2D web in 1993 where people wondered if it would go anywhere. He quoted Steve Kleinhans (VP Research Gartner) "The biggest market opportunities happen when we change the way people interact with computers". Activity in digital communities: creative quadrant, commerce quadrant, social quadrant and play quadrant. Presentation, User content, persistence (leaving tracks), social interaction, modelling (physics). Taxonomies of virtual worlds: metaverses paraverses. Prime time TV dropped by half replaced by YouTube. Animation vs Simulations using Finite-Element Modelling get realistic results. 100-fold improvement in server capacity for each user. 100x the network bandwidth required. User content is computationally expensive. He also talked about trusted identities in Cyberspace. My argument is all you need is reputation (unknown identity) or trust (known identity) not digital identity.

Interest post about how people read web pages. I'm doing this project where I have to handle several terabytes of web site data. I've thought characterising web pages by just recording the shape of the text. The article quotes research where most people web sites in an 'F' shape. It would be interesting to try and describe blogs by their shape.
