I started working on Slipper because I've long been a fan of the missed connections section on Craigslist. Each post provides a genuine glimpse at human action (or inaction) and the resulting vulnerabilities. However, I've been frustrated with the ineffectiveness of the current system. The ultimate disappointment of missed connections currently lies in the fact that most posts die a quiet death in the endless internet ether.<p>Slipper takes on this challenge through algorithms that continuously match posts to people. We determine the probability that each post is about each of our users, or that a user may recognize the target of the post. If the algorithms provide a strong signal, we send the user a push notification telling them to check out the relevant post. Our servers are continuously calculating these probabilities to create a fresh experience each time the app is opened.<p>Still early stage, but I'd really appreciate your feedback. Thanks!
