, seven commercial space for nonprofits and that sort of thing. [inaudible] are there any modalities for sharing their? >> the question is there's a lot of vacant commercial space that could be mobilized for civil society, so is there a way to do that? >> i know of one company, loose cubes. i'm sure there's others that many of you know there. >> i see mark in the audience there. do you want to explain what liquid space does? i think it answers the question, actually. >> [inaudible] [laughter]

>> mark really got my attention recently. it launched a couple of months ago in san francisco and showed me his application on the iphone and made the statement that if we use all the commercial real estate that we have, we would not need to build another building in our lifetime. so then asked him if he could write an article, so be careful what you tell me. ok, so, i was told one more question. anyone else to close it out? in the back there. >> [inaudible] > i guess, what i'm wondering is where do you see opportunities in this area?

one of the exciting things about this is actually how we are building trust between people. >> the question is -- what are the barriers around trust, and what are some of the opportunities, right? >> i can start. it is a great question. i think trust is probably the main barrier all of us face to get people over that hump of trying this experience for the first time. i think there is a major opportunity in trust and reputation-building for all of these collaborative consumption companies to work together. if you are a mentor and leave the place spotless and have been a good tenant, can you then rent a car on get around and bring that reputation with you so that people can see that you have participated in other sharing companies as well? i think there is a huge opportunity there for us to

collaborate. there's a lot of companies hopping up in a specific space looking at the problem. i am advising a new company called project trust, which has no product yet, but just a general mission statement around this area, which you might find interesting. i would say there is a lot of innovation that needs to happen there, and i think we can all work together to help cultivate trust across communities. >> i will push back a little bit. i do not think trust is as big a barrier as what i have been hearing. a recent study by a pr firm found that trust in big institutions is at an all-time low and that with that is an increase in trust in individuals and trust in each

other, right? i think that is a huge opportunity. this is why it is happening, i think, and the sharing economy is emerging now. part of the reason it is happening is that social media is sort of like sharing training wheels, you know? you can share a link or remix a video with people from around the world and see how will it was, and it is easy and low-cost and not risky, but there's a certain logic there that easily translates into the offline world. we did a survey, the first-ever survey research about sharing attitudes and behavior, and it showed that 78% of social media users were -- fell likely to share offline also. i think social media is like this, the thin edge of the wedge of the schering economy. it has kind of open the doors. -- of the schering -- the

schering -- the sharing economy. that is our last question. i want to close quickly just by saying that our view about technology is that he is not an inanimate object that controls our destiny. it is something that we decide and what we want. i feel like this is a very constructive conversation that is a stark about what kind of society we want to have, what kind of people we want to have. i want to thank the mayor, spur, our awesome panelists for a very rewarding panel. thank you.
