I'd say WordPress is worst in class for security, compared with all other software and all operating systems. WordPress even has a folder for hackers to put plugins that will not show even to administrators! I've never encountered any worse software than WordPress for security and usability, and I doubt it is just because of it being everywhere.

It is amazing how much time and effort in the world that has been lost because somehow it became the standard.

Quality WYSIWYG editors and hosting tools will come back with a vengeance soon. As soon as austerity and efficiency returns to the economy.
