McKinsey has a great new interactive tool to track advances in how businesses are using Web 2.0 technologies.  The data behind the tool is the result of three years of surveys, and the input of some 1,700 executives from a variety of fields.  From the McKinsey description:

This interactive focuses on several of the survey’s core questions—from what technologies and tools companies view as most important to what kind of investments, if any, organizations plan to make in Web 2.0 in the future. Our survey examines the business use of 12 technologies and tools: blogs, mash-ups (a Web application that combines multiple sources of data into a single tool), microblogging, peer to peer, podcasts, prediction markets, rating, RSS (Really Simple Syndication), social networking, tagging, video sharing, and wikis.

Using the interactive, you can track the performance of each technology through the years or customize the view to compare particular technologies side by side. The interactive also contains an audio guide from Michael Chui—a consultant with McKinsey and one of the drivers of the Web 2.0 research initiative—who takes you further inside the results and trends.

Here's what the tool looks like.  In this view, it shows which technologies executives find most useful to their businesses.  Click here to use the interactive version.
