Dan's Response

Hi Byronn, thanks for the questions. I imagine the Wolframs and Arthur Benjamin would be able to better answer them but I can tell you that I use Wolfram Alpha not as an end unto itself but as a means to an end. For instance, I was recently trying to answer this question and it resulted in a complicated equation with a radical. I fired up WA and entered in the equation and WA handled the calculation. Again, I handled the creative thought of coming up with the equation. WA handled the brute force solution of the equation. That's more or less my approach to educational technology. Regards, Dan Byronn's note: "this question" refers to http://threeacts.mrmeyer.com/tacocart/, which was down at the time of this post.
