Amazon Mechanical Turk allows people to pose questions not easily answered by a computer; however, a form is needed to collect the responses. Given Wufoo's familiarity with forms (great for collecting information), and Mechanical Turk's specialization with Human Intelligence Tasks (great for facilitating questions) integration between the two products allows for great knowledge gathering.
The Wufoo form builder allows for the drag and drop creation of forms -- no programming needed. Validation and smart fields are built in.
In addition to making data easy to collect, the data is easily accessible through email notifications, RSS feeds, online reporting and an open API.
