Interesting data on the rise/fall of music delivery - eye-wateringly ugly animated GIF - Tufte would have a field day with this. Small multiples or better, to show trends, sparklines or animated bar charts (reminding of EQ sliders) to make it much more obvious and easy to read.
Agree that looking at the data, in the midst of the rise of the CD, it would've been easy to think, as a music executive, that it would last forever.
But even James Bond knows CDs aren't forever. ;)

A reader mentioned this list of tools - quite the collection. Great to see that iPads and iPhones, as well as other smartphones, and the increasing sophistication of web apps, is driving an explosion of options and competition in the thinking apps world.

"From smart phones to iPads to our various personal computers and data managers, we have all kinds of tools at our disposal to help us collect information for school work, business, personal use, and more. But even though it’s easy to find, that information still needs to be stored, saved and even shared in a way that’s also simplified."

Just stumbled onto this - a free visualization tool that uses a variation of TRIZ modeling standards. Windows only.

"A universal visual language. Use Southbeach to model any complex situation in fields as far flung as finance, engineering, management, the law, global issues, education, marketing, the service economy, health care, information technology, strategy or politics. Add perspectives to your models. What is useful? What is harmful? From which viewpoint?"

Nice collection of stencils for OmniGraffle (essentially, Visio for Mac OS X) - handy for search, taxonomy, IA mockups.

If you're interested in visualizing your Twitter activity, here you go. Writeup on Mac setup, and link to generic setup using Google Chart API.

Here's a site I don't view nearly often enough. If you admire (and aspire) to understandable, and even pleasing information presentation (ala Tufte, for example), you need to go here. Now! Really!

Brought to my attention by Ed Gandorf at MapInfo. Interesting collection and peek into a huge array of visualization methods. Many ways to show data, strategize, paint timelines, etc.. Reminds me - if you haven't been to one of Tufte's one-day courses - g

Nice javascript-powered "lightbox" - may use to embed photos/screenshots associated with podcasts

great charts to show growth of adoption of consumer electronics, and other such things. Found by reference from Guy Kawasaki's blog

a "lens" from Dave Gray at xPlane on how and why to sketch, good examples (lots), and ways to think about when sketching might be appropriate, how to improve, etc.. For Visual Thinking.

interesting time-based visualization of conference IRC backchannel talk - who's talking, about what, etc..

an applescript that uses OmniGraffle to map an iTunes library, look for the most popular/highly rated tunes in your library. I have not run it yet...

using social bookmarking to jumpstart REAL tags for navigation/search by the popular tags... is this deep, or not?

PDF of presentation on card sorting - more detail than most

Methods to analyze card sorting results

Great list of companioins to del.icio.us - both web-based and 'native' or Java-based clients
