What is Web 2.0?

From what I've read, Web 2.0 is more of a community- based environment than Web 1.0. Everyone is a part of it....everyone can contribute. We can all learn from each other rather than just learning from the 'experts.' Instead of the dictatorship of Web 1.0, Web 2.0 is a democracy! Yay!

The 7 1/2 habits

I think for me the easiest habit would be Habit 1: Begin with the end in mind. That seems like a no brainer to me. Why would you do anything if you weren't doing it for the end result?
The most difficult would probably be Habit 3: View problems as challenges. I'm more likely to view problems as obstacles. I have to work on that one!
