Physical Vicinity
Using Bluetooth as the only means for communication between users, denotes that sharing of thoughts is only possible between users that are physically near each other. This means that while your Urban Thoughts are posted on the digital layer, through the application on your cell-phone, they are at the same time restricted by the physical layer, namely the actual physical context within which you are present. This brings the digital layer closer to the physical reality in which you find yourself, because the thoughts you sense from other people are irreversible related to the physical reality in which you are.
Complete Anonymity
By allowing for complete anonymity, the only thing people viewing your Urban Thoughts know about you is what you post. This means that it is entirely up to you not only what, but also how much you post – people sniffing your Urban Thoughts will never know anything else about you than what you post. Thus can you share your most intimate or most cursory thoughts with other people, without them ever knowing who you are.
