The key is building a community - The White House blogs on success with Drupal
A couple of days ago I stumbled across by Peter Welsch, Deputy Director of Online Platform for the Office of Digital Strategy at The White House. He talks about the improbable way open source software is built and how it can benefit organisations and the success they've achieved thanks to Drupal and it's community. It is an interesting read.
You say sure. When she returns the screwdriver a couple days later, your friend mentions that she made an improvement: now it works with both Phillips and flat head screws. Another friend hears this and asks if he can take a look, too. When he returns the screwdriver, it's been upgraded again: now it's a power screwdriver. Then a third friend gets excited and adds some extra speeds and a better battery.

Contributing back to Drupal
The White House recently created a Drupal.org user account and have created a poject FortyFour, a base theme currently in alpha. They also have a Git Repo containing open sourced Drupal modules. You can hear Tom Cochran talk about the "We the people" project which he presented at DrupalCon Denver.
It will be interesting to see what developments occur during the next presidential term and what positive impact this has on open source adoption beyond government.
