Come ON guys: It looks like you are missing it! It looks like you could go live, start getting okay revenue, 'bootstrapping', and doing 'organic' growth NOW.

Come ON guys: It looks like you are missing it! It looks like you could go live, start getting okay revenue, 'bootstrapping', and doing 'organic' growth NOW. Notice something really special about your application and your users: You are LOCAL, geographically LOCAL. So, if you want to get users in, say, Boston, then it's essentially irrelevant what you are doing in San Francisco, New York City, Miami, etc. Sooooooo, to get started with only a small, tiny, cheap server farm, get started in just ONE city. When you have some good 'traction' and/or revenue from that one city, expand your server farm, etc. to another city, say, an adjacent city. Then grow across the country and world this way. Besides, your ad revenue will be similarly local. So, you don't have to bite off the whole country in one bite to be successful and, instead, can do well one city at a time. Also, this fact gives you a 'geographical barrier to entry' since when you are in Boston you have no competition from a company in San Francisco or Miami.
