Might as well just use vanilla HTML, CSS and JS... no?
It seems just like Angular to me - and worse, buggy Angular: how does "Born on time property="birthday" datetime="2014-06-01" 1 Jun 2014 /time" get transformed into "Adam Catlace Born on 1 May 2014"? ( http://mavo.io/docs/primer/ , current Google Chrome, version 58, no extensions, no weird timezone one month behind the rest of the world)
The language does seem nice for the tasks at hand, and the learning curve looks shallow, but you are overhyping it way too much ("no programming", "better readable").
