It would be very helpful for all web developers to know which usability tools were most popular. Ideally, we would all know which user interface design tools were used by successful website developers and usability professionals. There are so many new tools now available (at least 300), that it would be difficult to do detailed evaluations of them all.
One way to ascertain a tool’s popularity is to see how many are using the product’s website. We assumed that the more people accessing a tool’s website, the more that were using that product. In other words, the better the rankings, the more popular the product. This is a form of ‘crowdsourcing’.
