and, but and commas

[Ruby]

I was always taught that you should not precede 'and' by a comma, since it is a conjunction which provides the space/break between two phrases/clauses in itself. Similarly for but, when it is in the middle of a sentence. Ruby certainly corrects to this form.

I do, don't I? Although, there are times when I don't.

In my business writing, the style chosen often depends on the style guide that is preferred by my clients.

Rose is right on target. Pick one method and use it consistantly.

However (and I am told one should not start a sentence with however, nevertheless, etc., too - but personally I think that is rubbish and shall continue to do so, so there!), I believe it is more and more prevelant to use the comma before but and and where they are conjunctions: what do people think? Is this acceptable style, nowadays? Is it a change in the language, and (see!) we should all start doing it? Or is it just a really bad habit I have???

Thank you all for your opinions!

Who says you can't start a sentence with "however, nevertheless", etc? Strunk and White give their approvals to do so.

Well, I have changed Instructors' and a few other things. I can see Louise's point about the play on words with Writer's. Basically, it is 'wrong' both ways, and the pedant who lurks somewhere in me is still inclined to change it, but will be interested in other views.

I can even see it being named, The Writers Block, as in a place for more than one writer.
