Hello, I'm spanish (from spain xD).
And yes, there is a difference between spanish in spain and spanish in an american country. But, I think there are differences even between the different countries in america.
There are words that have different meanings depending on the country, and there are different uses of some verb forms, but, still, I can talk with anyone from argentina, or venezuela, and we will understand each other without a problem. In fact, one of my best friends is from Argentina and we talk everyday, and when we talk, I know if he says "colectivo" he means "autobus" ("bus" in english ^^), I don't even have to ask him, but you won't hear me talking about a "colectivo" because that word has other uses in spain.

And, yes, if I read a text, I can tell you if the person who wrote it is from Spain, or from America, and probably I could tell you if he/she is from south spain, canary islands, mexico or argentina.
But, it is similar to english or am I wrong? isn't english different in Uk than in EEUU?
