WordPress is an Open Source system that was born in the mid-Atlantic as a collaboration between Mike Little and Matt Mullenwegg. Matt went on to set up up a company called Automattic which has carried on developing the system to this day. His company is based in Texas. They have imbued the system with some US personality.
WordPress has many many benefits and the few american idiosyncratic issues are a small price to pay for a powerful, simple to use and free website system.
