Enabled by the connectivity and community sourcing abilities of the web, we’re now more than ever able to share what we know. In both real world meet-ups and online forums, people are coming together to teach and learn from each other.

The online, open source style of sharing has also inspired the rise of organized informal gatherings with the purpose of exchanging knowledge.
