Some mobile apps have this problem of empty bar - in theory the service is cool, but as there are not many users, it is not so attractive. There are not so many users, so others won't try and stay.
I have heard that there are companies that can arrange you some paid first users installations in selected cities, you can also select some of those users characteristics (ie. females, runners). Anybody have used such a service and could give me some directions to start with? Thank you!
