Where I live, there is a concerted effort to do the same thing. For a long time people in the area have been trying to convince the world that our region is the best. Best beaches, best food, best beer, best outdoor activities, best mix of weather, best music, best quality of life.
And then we all saw what happened to Portland, Seattle, and Austin once the word got out and everyone knew about these "secret" cool cities. So now we keep our mouths shut and enjoy our beer and beaches without all the tourists and transplants.
For now it's just the spreadsheet, (anyone can edit) but the website will be by done by Nov 11th.
That's the goal anyway, and then from there I could open source or just do weighted average input for people to rate their favorites w/ no login required.
So I can direct people away from where I live, so the prices don't skyrocket.
