Can the Open Government Directive lead to Accountability?

Thanks to Sunlight Foundation for being on top of this:

"The White House has just released the Open Government Directive.

In a livestreamed chat, blogpost, and document online, the White House has announced a bold new plan for openness in the Executive Branch. The result of months of interior conversations, and three public components, the new policy introduces sweeping goals and initiatives aimed at bringing citizens closer to their government, through technology, information, and public interaction."

Here's my (admittedly skeptical) take:

WHERE DO WE GO FROM HERE?
Now that they've unveiled their plan, it's up to us to try to hold them to it. It's a pretty big task, and I'm wondering how they're going to accomplish it--not to mention how they'll incentivize agencies to cooperate.
