For me personally, the only reason I know what MtGox is, is that I've heard it enough times in relation to Bitcoins that I've made the connection. I don't know anything about bitcoins and I don't know anything about the root of it's name. "Moz" will be fine in the same way that "MtGox" is fine. They put out a lot of content and each time it will reference and reinforce the name. I think dumping "SEO" from the name is a fine move on their part.
