Well, with only 1,500 words with which to work, at least it would be easy to learn. I assume it would have no verb tenses, and probably is a bit like a crippled Esperanto.
It's a little hard to be linguistically bigoted here. Even in Atlanta, loads of the billboards are in Spanish, not to mention Austin where if you aren't bilingual, you are toast.
So much Spanish, French, German, Italian, Japanese, Chinese .... hell, you name it ... has invaded the English language. Every time a new immigrant group moves in, a whole new slang starts seeping in.
Eventually, there will be some sort of global language, maybe not for several more decades, but the world is getting too small for it not to happen. I'm basically lazy, so I'd rather it be some form of English if only so that I don't have to learn another language.
