This weekend I released version 1.0 of my Entity Fields Builder (EFB) module for Drupal, which is intended to make it easier to build custom content types and other fieldable entities in Drupal. I've also created a new YouTube video demonstrating how EFB works and explaining how it can make Drupal site builder easier and improve search engine optimization at the same time.
Drupal is exploding in government. The value that Drupal core and its huge ecosystem of contributed modules offer government is of course at the heart of this increase in adoption. However a number of distributions targeted toward governemnt including OpenPublic in the US, WET in Canada, and aGov in Australia are leveraging building blocks of functionality into powerful systems that meet many government specific use cases.
There are many tools to help maintain code quality. Every platform or language, at least good ones, have lint or code sniffing tools to help clean up messy code, make sure items are properly documented, and keeps bugs from being introduced. Drupal has the Code Sniffer which is part of the Coder module.
The use of Drupal has exploded in municipal, state, and federal governments. On a federal level the most prominent example is the White House. Many top level federal agencies such as Energy.gov, Data.gov, and the EPA. An estimate from last March had 150 federal agencies adopting or soon to adopt Drupal. According to Acquia 24 percent of all .gov sites use Drupal.
