Your reference argues not to start with usability tests before doing a design. This is not what I suggested, since sugar as a design is largely complete at this point. The article also. dismisses usability testing as worthless (despite backing and filling a bit toward the end). I don't agree. However, I assume from the supplied reference that you are stating that there hasn't been usability testing of sugar. This is unfortunate. I think it has real problems, some of which could be fixed through careful observation of its use by its target community in the context in which it is intended, namely classrooms with relatively low adult-student ratios. This is a matter of improving the affordances of the design. Simply asserting that any problems can be overcome by learning how doesn't seem responsive. <br>
<br>A good example is the rococco color picking widget. According to my observation this is very difficult for small children to use, and to learn. Swatches would be much simpler, with some way to invoke a fully general picker for the more advanced user. This is the type of issue that would be readily seen (and with an open mind, corrected) through usability testing.<br>
