If this assumption is correct with some cultures, then which cultures don't use punctuations?

Don't you think the SMS is the culprit?

however, not all native English speakers write or speak grammatically correct.\n\ni spot an error that could be overlooked by many in your sentence. "........., the first thing they usually mention is.."\n\nwould be better if "...........the first thing they usually mention has.."

Love does not sees languages. It doesnt sees the color or culture.it looks upon the adjustment from both.

It is a colloquialism. It depends on the geographical area where one is educated. It is ambivalent in that either way is correct.

Dear Friend:\n\nExplain what and stuff.  (First example)\n\nIn a world without grammar I would go nuts.  I have no respect for those who cannot use the language properly or communicate well.  I cannot abide constant misspelling of words that is not due to English as a second language.  I will not read anything that someone has butchered words such as "with" with "wit".  Its not cute, its not cool, it makes the person look absolutely stupid. \n\nI refuse to read anything that is not paragraphed at all.   I am not usually so harsh, but this is my pet peeve.  GBYou

Amricans use English but call it American language, they use dates, but use it wrong way and call it American style.\n\nAll the other countries use dates like 1st January 2007 etc, but Americans will say January 1st 2007. A bit wierd if I personally say so, my own view.

Neither is correct an apostrophe is only used between the last letter and an "s" o an "nt" to indicate a missing leter fo stance can't is can not ("no" missing) so Paul's would indicate Paul is ("i" missing)

In the U.S. the preferred past tense is "spelled," although "spelt" is not incorrect. "Spelt" is chiefly British.

Though I am a lawyer, I cannot understand your question, as it appears to have been written in the e e cummings style of no punctuation.  Sorry.

I'd like to think that most people don't care, just because it's Yahoo Answers or the Internet, but the same people that don't use spell check here, probably don't use spell check anywhere... Know what I mean?

I don't really think it's comparable because what may seem like common sense in one culture isn't in another, so to say one culture has more common sense than another is pretty much a biased point of view either way.

It is always going to depend on the sentance, of course.  But in that particular one, I would personally replace the semi colon with a regular comma.  \n\nThen it would read like: "Nothing is truly difficult when done correctly, so you should be completely relaxed."

There are certainly examples of infections being created, for example the future tenses in modern Latinate languages like French and Spanish, which were formed by adding "I have" "you have" etc to the infinitive - something like I have to go = I will go.\n\nOn the face of it, there does seem to be a trend over hundreds of years toward simplication; we see it in Latinate, Greek, Germanic, post Sanskritic, Iranian, and outside Indo-European with Arabic, and I think with Chinese (not sure about this one!).\n\nOn the other hand, it seems that the complex systems of the "classical" languages are themselves derived from much simpler systems that became more complicated as the languages evolved. Moreover, it is fairly clear that written classical languages preserved archaic forms that were already remote from common speech. Maybe it was the advent of writing, and the development of a literate elite that vied with each other to maintain essentially obsolete forms, that led to the apparent complexity of those written languages.\n\nGood question, I wait to see some other answers!

I can't think of a single culture that had a calendar and did not have an approximately 365 day year. It's just something you notice, and it's not really avoidable.
