I used baking soda toothpaste once in my life...it was salty and unpleasant. Maybe some people can deal with that, but in my mind, the minty = fresh association is the one that controls my toothpaste purchasing:)
Looking at the pictures, I don't get how the device cleans the outside of your teeth.
I honestly can't see this achieving mass market success for a few reasons. First, the price needs to come down - as a consumable item, people aren't going to want to blow a lot of money on it. Then there are issues with cleaning / hygiene - lots of crap can get stuck in those bristles. Then there's the risk involved - people aren't willing to risk their dental hygiene on an untested / unproven technology. For most people, this means a recommendation from their dentist / hygienist.
Well, box plots and bar charts have very different purposes...box plots are used to show distribution statistics, whereas bars are for comparing individual values.
100% agree on the pie charts though - in fact, the percent completion property of pie charts is perhaps the only thing that makes them useful. Imagine a scorecard with many rows of data, that uses a partly completed pie to represent a percentage value (e.g. half a pie = 50%, three quarters of a pie = 75%). Now, sort the data by the pie column, so the pie grows/shrinks as your eyes move up and down the scorecard. It's a very quick and useful visual representation because it provides a vertical reference for finding values near a certain percentage value. The cognitive delay that you normally experience with pie charts (of converting a slice to a percentage value) is irrelevant because the sorting makes it so that you only have to do this conversion once for many rows of data. I call this a pie trend. You heard it here first.
The problem is that most common uses for pie charts give them a bad rep in the dataviz best practices community. Have to agree with Few on that one.

This is just the latest episode in Stephen Few's war on pie charts. For anyone interested: http://www.perceptualedge.com/blog/?p=1492 http://www.perceptualedge.com/articles/08-21-07.pdf
The problem is they have a blind eye when it comes to a really overbloated defense bill
Heh. "Defense" bill.
