I see people build awesome sites, with loads of features, fast, beautiful and still they don't go anywhere. So much effort is often misguided. 99% of the site early growth depends on interesting conversations! "Interesting" is not just some fascinating or helpful information - rather it's about emotionally relatable stuff. Things that make people want to jump in and comment or share their own little something. It's often subtle, but somehow engaging. Like, say, "the sexual tension between these two beach houses".
