Clearleft has finally released its much anticipated usability testing software called Silverback. The site points out that usability testing is often very expensive, and time consuming. Silverback attempts to fix this problem by providing easy to use software that runs right on your Mac. Plop a subject down and record  every interaction they make. I’ll be downloading the trial version so I can test it out on GoLark v2. Check back for the results of my trial run!
