Language evolves. No denying that.
However, the English language, (and I should imagine the same goes for other languages), usually takes a few hundred years to change to an appreciable difference between the 'original' and the 'modern'. Someone mention the word doth and does. Yes, they both mean the same and the former is very rarely used today except when someone is either quoting a past works or simply pretending to be clever.
The problem these days is the language is changing so rapidly, because youngsters are not educated to as high a level as past generations have been, that the definition of words is also allowed to be changed without reasonable cause. Take the following example.
1969 That music is bad. Definition of the statement means the music is not of good quality.
2000+ That music is bad. Definition of the statement means the music is considered excellent by the younger generation.
This kind of 'reversal of definition' can only lead to confusion for generations to come who will interpret written words in the way they personally decide to define them. A lot of poor work may seem to be classed as good to certain members of society because they don't interpret the words according to their original definition.
Punctuation can make the same sentence appear to mean different things depending on what punctuation is used. Without punctuation words become meaningless and open to a wide variety of interpretation. Unless the Academia who conduct these surveys stand their ground and show that omitting punctuation, (be it a full stop, comma, hyphen, apostrophe etc), can lead to misunderstanding with possible disastrous results for both sides then there are going to be a lot of angry, misinformed and misunderstood people walking this earth in the future.
And if anyone thinks my full stops are a sign of anger then they are wrong. I'm irritated that these kind of things are being allowed to happen because some people are so easily offended these days but tough sh*t! The language has been this way for much longer than anyone on this earth has been around and it should stay as it is.
