For someone like myself, the biggest challenge will always be that the alphabet (abjad?) is unfamiliar. I am aware that it's rtl, and that letters are connected (and have different initial, medial, and terminal forms... as in Greek sigma, or some Hebrew letters). This would be accessible to more people if you included something to learn it first. I've discovered that once I do learn an alphabet, I can pick out cognates and other such words enough to make that worthwhile even if I go no further. I was planning on devanagari or hangul next though.
