I can read Korean but not Chinese or Arabic. But even if I can read all those foreign characters, most internet users can't, so better cater to the majority if you want (better) results or at least a number of replies here.
I think the Arabic might definitely be a drop. Don't hold me to it, but I wouldn't have purchased it. Seems like it's a bad version of "Bloggers" ??? Not 100% sure, so don't hold me to it!
