Who’s online right now? The public can track which federal Web sites are most popular.

The public and federal agencies now know how many people are clicking on the biggest federal Web sites at any given moment, starting with the most popular. The analytics dashboard, launched in the spring by the General Services Administration’s 18F digital team and Office of Citizen Services and Innovative Technologies, working with the White House, is designed to improve the public’s notoriously slow and painstaking customer experience with the federal bureaucracy. Think of Analytics.usa.gov is a sort of Google dashboard for government, which refreshes every 15 seconds. For now, a little more than 20 percent of the the 1,350 federal Web sites are participating in the project, but they include domains from every cabinet-level department and close to 400 executive branch sites.
