A comprehensive list of SaaS public health dashboards

To anyone looking to build a public health dashboard for their own online service, the following list should give you a head start in understanding what's out there. I also keep an up-to-date list in my delicious account that you can reference at any time. I would suggest reviewing the examples below when coming up with your own design, potentially combining the various approaches to create something truly useful to your customers.

Note: This list is divided up into three tiers. The tiers are determined by a rough combination of company size, service popularity, importance to the general public, and quality of the end result.

Tier One

• Trust.salesforce.com - System Status (http://trust.salesforce.com/trust/status/)

Don't forget to also review the seven keys to a successful health dashboard, especially since not one public dashboard I've come across meets all of the rules.

Again, the full list can always be found here. If I missed any public dashboards, I'd love to know...simply point to them in the comments and I'll make sure to add them to the list.
