While rulemaking is a relatively unknown process in government, it touches almost every facet of life. In fact, agencies make over 4,000 rules every year, with far-reaching implications for citizens. These rules determine how food safety is audited, who will have access to government health care, and whether polar bears are considered an endangered species. When agencies develop rules, they are required to solicit public comments and take those comments into account before the rules are finalized. However, while technically open to any and all, the rulemaking process is effectively hidden - and is ready for innovation online. We can increase public participation in the regulatory process using tools like social media and online communities.
