InMotion hosting has published a great post called WordPress Through The Ages, breaking down the CMS into a timeline of each major WordPress release, highlighting the major feature releases on it’s path to the software we all love today.
In Motion says: Through the years, WordPress has evolved into a powerhouse CMS. With its roots in blogging, it has turned into a major content management system that is flexible and extensible to do anything you could dream of.
They follow with a screenshot breakdown of the default theme and WordPress admin UI’s through the ages.
I dare admit that I remember the WordPress 1.2 release, and still love that bright blue colour on WordPress version 2.0.
Check out the original post for some WordPress reminiscing.
