Seems like a interesting little domain, although it seems WAY too similar to yaXay, which is probably what your idea was when you bought it. But it's still nice and brandable.
I agree with Static. Word of mouth advertising isn't going to be easy with this domain by any means. I assume "yaxay" and "yaxie" are pronounced the same... as "yaxay" is already an established brand its going to be hard to move away from there image.
Ive never even heard of Yaxay, but they do seem like a pretty established site. But saying they are to similiar isnt right. Im sure there are many well established sites that are similiar. http://doogle.com and http://google.com. Sure its not like Google, but still a decently visited site.
