Designing Web 2.0

In the logo design trends article I mentioned a few days ago one of the trends was "Web 2.0" Logos -- loosely defined in the article as featuring bright colors, icons, 3D effects, shiny surfaces, and other characteristics "synonymous to a modern and trendy logo."

Seems a little vague but then for most of us, the whole Web 2.0 thing is a little vague too. So what is Web 2.0?

About.com Web Trends Guide Daniel Nations calls Web 2.0 a social web and an interactive Internet. Our Web Design Guide Jennifer Krynin discusses some of the technical side of Web 2.0.

She writes:

Web 2.0 is starting to mean the situation where amateur writers and developers are able to create applications and Web sites that get more credibility than traditional news sources and software vendors.

There's something in that statement that sounds a little bit like what happened with the development and perceptions about desktop publishing. At first it was software for the professional designers. Then the easy-to-use consumer programs put desktop publishing into the hands of non-designers. Defining desktop publishing is almost as confusing as defining Web 2.0.

If you're expanding into or specializing in web design, you'll want to learn about Web 2.0. If you already do web design, how much of a role does Web 2.0 play in your design decisions?
