Dropplets is a super simple blogging platform based on good-ol’ text files with markdown. Basically it is a little FTP script that uploads your text file from the back-end. No fuss, no muss.
Anchor CMS is a super simple and super tiny content management system with the express purpose to “Make blogging beautiful.” Regardless of hyperbole the entire install package is just 150kb! That’s smaller than just the images folder of the WordPress install.
