colinneagle writes with news that Facebook is beginning to roll out tests of "want" and "collect" buttons in an attempt to bring users and retailers closer together. "The company is working with Victoria's Secret, Pottery Barn, Michael Kors, Wayfair, Neiman Marcus, Fab.com and Smith Optics. The difference between 'liking' and 'wanting' would be like discovering the holy grail of datamining. Inside Facebook said that although the 'Want' button is different than the Want plugin that developer Tom Waddington noticed in June, the company may eventually offer it as a plugin. Unsurprisingly, Facebook wants to keep people on the site as opposed to leaving to visit Pinterest. Collections will offer retailers a Pinterest-like option to engage buyers, offer users a way to collect images, while also collecting even more data about users. For example, Facebook asks, 'Why are you collecting this?' Regardless of a user's answer, the wants and collects will surely be used to deliver targeted ads. Eventually, the Collections feature could help Facebook generate more revenue."
