> The classic formula for hooking up is time and proximity - throw people together in the same space and wait - people will start hooking up. No app can provide this - they are designed with the exact opposite scenario in mind. Yes, 100% this is correct. Proximity is everything. When people "bump" into each other frequently, they are more likely to start conversations, more likely to get to know each other, and naturally, hook up. This is why the "third place" concept is so important. Home is the 1st, Office 2nd, but you generally need another place where people just hang out. This might be a community pool, garden, plaza etc. Somewhat more restricted 3rd places are coffeeshops, bars, art galleries, museums, libraries etc. I believe that cities that want to attract people should invest heavily in creating these places. e.g. Austin built a First Class public library; I was extremely skeptical about that investment, but when the library opened, its a work of art!
