Anyone can use open source software
Another great thing about open source software is anyone can use it, contribute to it or provide services for it.
You don't need to be a large company like Acquia or Red Hat.
I was a self-taught solo hobbyist Developer when I started building a website for my local Tae Kwon-Do club in 2007 with PHP.
In 2008, I started learning Drupal, built my own website and started doing freelance Drupal development and consulting work.
I became a full-time Drupal Developer in 2010 and haven't looked back since.
I was able to this for free using open source software.
