"Here are few of the best screen recorders that will allow you to create videos and presentation from your activities and which are free to use" (¶1, 2010.04.13).
I'm not sure if all the items reviewed are as insensitive, but the CamStudio link merely takes the user to a PC download link without even asking concerning the system that the application will be running on. It is typical of Windows users to assume that the entire world (that they're interested in) uses PC computers. I have not tried it, but for Mac users, I have had IShowU (free program) recommended; Linux users probably also have some options that are available, and perhaps others can share what those not running PCs on Windows use for screen capture.
