Absolutely. You practically "took the words right out of my mouth", @Stevie_D
I have witnessed a gradual but continuous degradation in spelling and grammar in America (and on the Internet). There are numerous discussions (and arguments) against the merits of proper spelling and grammar. Although I agree the root issue is 'getting your message across' I am a staunch proponent of correct language usage.
The English language (and let me disclaim that I do not speak English. I speak American) possesses the richest vocabulary. This is primarily attributed to the fact that it has 'borrowed' from almost every other language that has existed!! I propose that it is mere laziness to avoid stretching your vocabulary and seeking ways to express yourself more precisely.
**steps off soapbox
As is the case with anything, if you are learning English (of course, I just made the point that we ALL are constantly learning English) mistakes are to be expected. And it is easier to be tolerant of mistakes over laziness. There are many very confusing words and uses in English. And numerous [common spelling and grammar mistakes. But, as [URL="http://www.wistful-thinking.com/archives/237"]I have done here](http://www.wistful-thinking.com/archives/237), you should learn ways to overcome the human tendency to err and not be content with "good enough".
