With the recent release of a modified version of their search engine, Google is receiving praise from many different groups. The new Google Accessible Search was released as a Google labs project which prioritize pages based on their likelihood of being accessible to visually impaired users after the original search results are returned. From the article: "The best-known guidelines for building an accessible site are the Web Content Accessibility Guidelines (WCAG) from W3C. But these are not the basis of Google's new service. Raman said: 'We don't test against WCAG. We think in the spirit of those guidelines, but we don't test against them verbatim.' Instead he endeavored to identify 'what works for the end-user,' describing a process of 'experimentation, training and machine learning.'"
