We built Callroulette, a chatroulette for phones

In plain words

Callroulette is a phone-based chat service that randomly connects users for conversations. Launched in 2011, it applies the chatroulette concept to voice calls rather than video or text. The service is designed for people looking for spontaneous, anonymous phone conversations with strangers. It offers a simple way to meet new people through random matchmaking on mobile devices.

  Codecademy.com, the easiest way to learn to code▲787

  I've been a longtime member @ HN, but I haven't been a developer. In fact, my only HN submission has been one asking how to learn to code (http://news.ycombinator.com/item?id=820741). My cofounder and I decided to solve the problem by making a simple, interactive way to get started with Codecademy. We'd love your feedback. If you're interested in helping us to get more courses up (on any topic!), please send us an email at [email protected].
