Lukas Wallmann was Web developer for 8 years and simply nerved about the existing stytems. He thought they all are to Big, loaded with functions noone really needs but when it comes to editing they are only a wysiwyg editor with an save button.
He decided to not use MySQL as on Heavy loads this is not scaleable enougth. By Working with admin/data/__sitelist.json you could easily see how a cms could work to. All you need is to run json decode in your php and you got all data you need.
Lukas is 26, got 1 child (Emma), and lives in the mountains of Austria.
