I’ve uploaded the current version of my usual presentation to SlideShare. It sets virtual worlds in the context of Web 2.0, as well as giving a potted history of my interest in Second Life and current IBM activities in the area.
Click through to the presentation itself for some handy links on many of the slides. Feel free to add your own comments and questions to it as well. On my own blog there’s a fairly detailed overview of what I actually say when giving this presentation which you might enjoy too.
