A worldwide community for Certified Usability Analysts
I realize this is an old post... Many years past since, and as it turned out Optimum Workshop did not replace usability consultants, but they did replace the free version of their software with one of the most pricey among all online usability tools. Granted, they decided to go after well-funded corporate teams, which left out in the cold a whole bunch of independent contractors and small UX firms. Later they bought WebSort, which was one of the oldest on the market and offered competitive pricing. That option is no longer available. Couple of years later, the one that came out as a budget-friendly alternative was usabiliTEST, which has been growing ever since.
