I love it when ppl directly ASK me to answer a question on Quora.com. I also enjoy when someone on LinkedIn sends me a direct message asking me to chime in on a discussion they started. I'm always quick to jump in and share my thoughts.

Here is my response to the question:

What are 5 Drupal strengths that other CMSs or frameworks don't have?

OK. You asked for 5 so I'll give you 7!

This is just off of the top of my head. If I had more time to articulate this and build it out it could be glorious. But here it is. ;-)

Community

OK. Many projects have a "community" but what Drupal has is incredibly unique. We thrive on getting together. Our national North American conference [DrupalCon] brings in 3,100+ ppl. Our regional events [DrupalCamps] bring in from 100 in smaller towns to nearly 1,500 in major cities. When we get together we share all our best practices and show the methods used to release our most recent projects. We also have CodeSprints where we actively work together to advance specific projects. Right now the focus is building Drupal8 for release in August 2013. Distributions

We don't expect ppl to always download Drupal core then build their own intranets or online stores or event management systems or news publication sites or Government portals. Instead we provide FREE distributions of Drupal that come pre-built for just those scenarios. See a full list of distributions available here: Distributions | drupal.org Market Share

We're have an impressive presence within the market share as a whole. The further you climb up the Alexa 2million list, the stronger we get as the others are dropping from view. We really are the OpenSource CMS of choice for some very serious, important, widely used sites for Government, Entertainment, and more. Developer Pay

This can be a curse and a blessing, but right now the income for a Drupal developer [or designer or themer or trainer, etc] is pretty dog gone high. This is a result of simple supply and demand. Many of us who saw a good thing years ago did NOT know the demand would be like this. Thus, here we sit today with a tremendous value being placed on our skills by the market place. The flipside of that is that some people failed to see this coming and have not jumped onboard and now we need a lot more talent than we have.

Drupal is a hybrid between a standard CMS and a very progressive Framework. We never claim to be CodeIgnitor or Cake or Zend, but we do have an extraordinary API that allows for amazing granularity of workflow control. Our implementation of "Hooks" and "Callbacks" through our clever "Function Naming Convention" hands the raw power of customization to the code monkey who's client is a control freak. We never say, "Ehhh... That's just the way Drupal does it. Live with it!" By being a rapid deployment system, Drupal allows more time for tweaking what needs tweaked or adding what needs added. Module Development Practices [BONUS ITEM!]

In Drupal everything is a module and ALL modules are free! We don't have plugins AND widgets AND components, etc. ALL Modules are listed at Modules | drupal.org and are well categorized. You will not find some ones personal website where they sell a module. If you want a custom module built you can find someone to build it for you.

We share our time and talents in building these modules together as a community. We don't compete. Rather than have 5 twitter modules, we have one twitter module which has many ppl working on it. We submit security patches and increased-functionality patches and UI enhancement patches and documentation patches to one another's modules so that they are the best they can be. Support [BONUS ITEM!]

CMS Support for Drupal Open Source Acquia Looks To 2014 IPO With New $30M Round - Forbes

Acquia provides a very strong "3rd Party Validator" role in winning bids. Shops of any size can, after winning a contract, have the client rely on Acquia for hosting, and/or Support and/or Training for the client. The Drupal shop can move on to build the next big Drupal project while Acquia supports the client. If a phase2 is needed in the future, the shop can choose to take on the additional work OR Acquia can help the client find someone who can.

Not every site launched in Drupal uses Acquia services and some use a little while others use a lot. The options are wide and deals are struck that cater to the needs of each individual client.

I could go on and on about how Acquia provides value to the Drupal community, the Drupal project, Drupal shops, and clients, but that would be a very long post. ;-)
