this thread has a necro fetish.
Anyway, SS, just so you know, there's no such thing as "Standard" English. There are the widely used ones, British, American, Canadian, and Australian, but each one of those has it's own little subgroups, and I'm sure there's plenty others (I think Hong Kong has a unique flavor of English)
This is mostly just slang and spelling, but there are the occasional grammar rules getting in the way, too. For example, in some dialects, nouns that include multiple people are plural (British English does this, I think, but American English doesn't), for example, if you look at a Wikipedia entry for an English band, it will say "<NAME> were/are", whereas an American band will say "<NAME> is/was", you can look at Aerosmith and Def Leppard's pages if you want to see this yourself.
If you want to learn a standardized language, English isn't the way to go. Might I suggest Esperanto or Ido?
