I think&#x2F;hope my start up, Krewe (<a href="https:&#x2F;&#x2F;www.gokrewe.com" rel="nofollow">https:&#x2F;&#x2F;www.gokrewe.com</a>), has found the right formula. I believe the key elements are access and comfort. Krewe places people into a group with five of their peers, making it comfortable to hang out at first. You don&#x27;t have to single anyone out, it works kind of how things worked in your youth. And everyone lives within a half mile radius, so it&#x27;s really convenient to meet up often.<p>As you say, having lots of stuff in common isn&#x27;t usually the defining factor in what makes people &quot;click.&quot; I think most people can get along with pretty much anyone, so long as they spend enough time together. When you&#x27;re in school, that&#x27;s built in since you have to show up to class everyday. Krewe makes it possible to hang out with your group everyday since everyone&#x27;s within walking distance and can get together for a quick beer or whatever.
