Why are Microformats important?
Microformats allow us to describe our content in ways that machines/apps can recognize and interact with it. For example, on your iPhone, a phone number can be clickable and will dial up the number without you having to type it in. There’s many other more useful reasons but I think an explanation like this really explains it well.
The Official Definition
From Microformats.org we can pick up some great uses and implementation practices. Emily is by far one of the most well versed people in this subject that i’ve met. Her book Microformats Made Simple is also a really great resource.
Designed for humans first and machines second, microformats are a set of simple, open data formats built upon existing and widely adopted standards.
