Great observation--came here to say the same, but I have to disagree that jumping from Hindi to Punjabi (for example), even with a little bit of practice, is simple.
I'm a native Urdu (Hindi hehe) speaker and though I can understand the gist of a fast-paced Punjabi conversation, jumping in to participate is whole different matter. Even with a little bit of practice, I doubt I'd be productive.
