1. Photsynth: It needs an active x pluggin for Internet Explorer, but it’s like using something from the future now. The way the navigation goes through the 3d environment is great and the way I order photos in a 2d model is superb.
  2. Google Maps – Live Maps: the entire map can be seen as a gigapixel image, street view is truly useful and the directions tools that both sites offer are a great way to show how web 2.0 apps are afecting nowadays rutine.
  3. Google Reader: the best way to keep you updated, it has a high performance and forget about having to check manually every feed either in your browser or surfing page by page. In 5 minutes I can overview more than 80 feeds. Apart from the mail web systems, I thinks this is the most useful web software available for professionals.
  4. Yahoo: the ultimate usability portal, well studied components which give the user a lot of information in one page.
  5. Flickr: great community where people can actually know the whole world with high quality photos taken from great photographers. It has great sense of usability (yahoo trademark), and you can spend a whole afternoon using it in conjunction with the apps described at point 2.
  6. Microsoft’s Hotmail: It’s fast to manage, I can do a lot of things faster than If I were using gmail or yahoo mail, it’s very intuitive with the “right click” options.
  7. iGoogle: the extensions and the widgets offered are great, you can actually set your internet “dashboard” here.
  8. Youtube: the ultimate web 2.0 site. Huge community, huge traffic, and very entertaining site.
