This article is an example of choosing easy option over the better option. From a startup's perspective, it's completely understandable. Thousands of cheap MySQL admins, or a few hundred expensive PostgreSQL admins? As for the "nobody uses PostgreSQL" argument; Facebook and Twitter aren't an endorsement of MySQL because any Linux hosting provider out there will have MySQL installed BY DEFAULT. PostgreSQL would require you to upgrade to a more expensive account (for root access) and install it yourself. As a result, all the hobbyists learn on the free and always available MySQL when building "The Next Big Thing." Remember, Facebook was started in a college dorm room.
