Discussion about a startup idea from SF

Hi guys! I lived in SF right now. Yesterday, I had lunch with my best friend who is currently working at Facebook. He really gave me a very insightful idea.

The basic concept is: Everyday, we want to buy something or learn something great. For example, when you want to buy a skateboard, you may think about Amazon. When you want to find a restaurant to eat, you may think about Yelp. But what about the gallery and art museum? So if there is a platform which you can find gallery info, current shows, and some cheap art work, that will become so much easier for people to get access to the art industry. In the future, the platform can have a magazine or sth.

How to you think about the idea?
