Who cares? This is boring code. Save all the "it portends an open government!" handwaving for once the Obama admin does something _actually_ meaningful (in a positive way - starting a new war doesn't count). Seriously. Much ado about a Drupal module that is used for people to petition the government to be patronized and ignored.
That's a pretty cynical way of viewing things. Take a look at the big picture: the highest office in the land (world?) is doing what we here on HN do: push public code, accept feedback, leverage open source etc. It's a fantastic start towards a new paradigm of open source code in public places. This should be celebrated; a new generation of people are running things now. It can only get better.
I don't think a new generation is running things. That kennedy camelot spin was used in 2008, but it is 2012 now, and I don't see any evidence to support it. (EG: Pick your issue, Marijuana dispensaries are getting raided, the PATRIOT act has been expanded, the Afghan war is expanded, the TSA is now molesting and taking nude images of travelers, etc.)
