I have been thinking to create a social network application built by using google earth api and sell/rent spaces for companies for their promotion on google earth via my web application. There will be a lot of coding and too much time will be spent on the project. So I am still not sure if it worths to make it. I am living in a town having a population of 60 000 and I want my application to provide users to walk and tour around the city and interact with the buildings which has companies inside.
Do you think it works ? How can I decide if it will work or not ? Is it doable ?
