That's one strange perspective that you have of Web 2.0.
I think quite the opposite. The 2.0 design style is pretty
colorful, but its the presence of sites that come off as raw. Part of the reason for that is because web 2.0 is made to be very user-friendly where Web as we know it is designed to be application-driven rather than graphically-driven. Internet is going toward the time where it will be served almost as an OS to computing... Not sure how many people actually share that theory though.
