Part of the whole Web 2.0 thing we're all hearing so much about is interactive content and services.  Folks want to be able to use the internet and not just have it thrown at them.  They want to be able to have their friends and family members collaborate to help plan vacations and look at photos and movies.

To that end, Google has added collaborative and interactive features to a lot of its services.  I've talked about Docs & Spreadsheets before.  I even made our calendar of industry events shareable through Google Calendar for all to see and use.  While reading the Google Research Blog tonight I ran across an interesting article about collaborative and cooperative work.  Some Googlers recently attended a conference and had the chance to demo some of Google's services and tools to the crowd of industry leaders and thinkers.

One tool mentioned in the post that I haven't really talked about is Google Notebook.  Notebook is a service that lets you create content that can be shared and accessed from anywhere.  You can save images, clips of text, or even entire webpages to Notebook and organize your saved information however you want.  You can make it public or send it to friends.  With simple browser extensions, you can access your notebook at any time from a small icon in the browser's status bar.  It's really a neat little service and it exemplifies what Web 2.0 stands for.

Collaboration and networking with friends, family, and co-workers is the future of the internet.  It's what Web 2.0 is all about.  Google has embraced that trend.  So has MySpace and other social-network sites.  YouTube… Blogger… WordPress… they're all about the exchange and sharing of information.

Where are you with collaboration?  What have you done to make sure your website offers something visitors can actually use?
