I have spent a lot of time throughout the years researching and collecting facts and stimulus materials on the topic of Computer Viruses. Recently when I was watching my regular TED talk on my phone I watched this talk by Mikko Hypponen. I found it fascinating for the way in which he not only explores and shows some of the history of viruses but also talks of the social and ethical implications of the contemporary viruses being releases. He explores the use of viruses from a cyber-crime and organised-crime perspective.
After you have downloaded the extension or add-on for Firefox or Internet Explorer (Chrome coming soon, very soon I hope) you can see other people that are viewing that page and chat with them in real time – pretty much like an Instant messenger. Of course the other people have to have downloaded and installed the extention too, so it will take a while to reach its full potential, but it could mean lots of new ways of networking with people.
