The question and answer social network Quora shocked the tech world this week, raising $50 million in financing that valued the company at $400 million. The company depends on both mobile and Facebook apps–do you think it is worth it?

According to research from AppData, daily average users for the Facebook application for Quora rose from 160,000 to 190,000 users since April 15th–adding 30,000 users in a month. At the same time, the Quora iPhone app is currently ranked at #98 on the Top Free Apps Social Networking Genre chart.

Here’s more about the app: “Quora for iPhone makes it easy for you to browse the information that is most interesting and most valuable to you. All you have to do is follow topics, questions or people and their boards (collections of information people use to share their interests).  People — real doctors, economists, screenwriters, police officers, and military veterans — bring a wide range of expertise and first-hand experiences to make the content on Quora high quality and enlightening. Discover content in over 60,000 topics on the fly, including thousands of location-based topics.”
