Here's a first: I'm giving a shout-out to a private healthcare company
Pharmspective is a company that specializes in healthcare industry data visualization/management apps. Most recently, they've announced a new app called "ACO Tracker" which basically does just that: Unscrambles information about Accountable Care Organizations, which are a Big Deal® these days.
Full disclosure: While they're not paying me to promote this particular app for them, they did pay me to help out with some data issues last fall, so take that for what you will (as an aside, in the process of helping them answer some questions which aren't directly related to this site last year, I also stumbled upon some info which is directly related, so that worked out nicely).
Anyway, I don't know much about ACOs myself, but as a data nerd it seems like a pretty cool app for those interested in this area, so what the heck: Check it out.
