The landing page is pretty good if you are familiar with Matrix.org, and I'm assuming that it's aimed at Matrix developers. Personally I appreciated the brevity, simple declaration of the problem it's trying to solve, and a quick link to the real call to action (the Git repo). EDIT: realizing that the landing page may have been updated with new content itself since your original post.
