Mainstream IT press recommends Drupal
The current Editor's Choice article at Information Week is titled "Everything You Need To Know To Get Started With Content Management Systems" and features Drupal prominently. Drupal gets mentioned first and receives high praise.
The article says this about Drupal:
Drupal is among the best known and most well-regarded content management systems, open source or not. This is due, in part, to the availability of dozens of plug-in modules that support everything from standard functions such as adding content and blogging, to calendaring, bulletin board forums, and photo galleries. Virtually anything most organizations could need is available, and there is an active, helpful user community to assist with getting everything to work.
Information Week is a print and online magazine which has been in circulation for over 19 years. They describe themselves this way:
InformationWeek is a weekly print magazine that reaches 440,000 Business Technology professionals at more than a quarter million unique locations. It is read by Business Technology professionals whose titles span the IT spectrum and provides unique perspective and in-depth analysis on news, research and IT trends. Our mission is to help Business Technology professionals drive business innovation.
Having read Information Week off and on during many of those years, I have no disagreement with that description.
I predict Drupal will be getting a lot more attention from traditional, corporate Information Technology (IT) staff in the very near future.
