You've probably heard of WordPress, right?
Think of it this way: WordPress is for your personal blog. If you need something more complex and powerful - go with Drupal!
The Drupal Experience
Editing Your Site
A friend of mine recently told me that he still needs to email his web developer if he finds a typo on his website.
I was stunned - didn't even consider that something like this could still be an issue in this day and age. In Drupal the editor of a website has a nice, user friendly interface to create and edit the content of the website.
You want to use your phone while waiting in line for your triple mocha latte, right?
How annoying that there are still websites that don't work well on mobile devices! The Drupal administration interface is responsive out of the box, and so should a web design.
A "responsive design" ensures that your site provides a comfortable viewing experience, no matter what kind of device it's viewed on.
Drupal is Open Source. What does that mean?
First of all, you can use it for free (yeah!).
It's also usually considered to be safer, any security vulnerabilities could be out in the open - which makes it more unlikely that there are any vulnerabilities in the first place.
It's about the community
I really like the Drupal community.
At one of the more recent events (DrupalCamp Michigan 2016) I gave a talk about the conversion of a module from Drupal 7 to Drupal 8.
