Pinterest is preparing to join Lyft as it's slated to begin trading. The content curation site remains popular mostly among women, and it serves as a repository for recipes, decor ideas, and aesthetic. Pinterest helps to popularize trends, such as the "Amazon Coat" and its successor the "Amazon Raincoat." Yahoo Finance's Dan Roberts, Myles Udland, and Kristin Myers discuss how much more Pinterest can grow after going public with Good Housekeeping's Style Director Lori Bergamotto.
