Originating from a comment on one of the SE sites.
Which one is correctly punctuated?
- "Nothing personal and, welcome to *.SE"
- "Nothing personal, and welcome to *.SE"
My understanding is that we use the comma wherever we have to pause, in speech and to help with connecting related phrases together. I was dumbfounded, because both sentences seemed equally cool (yes, I was trying to sound cool in the comment). I am willing to accept omission of the comma entirely as well, if 'and' is not followed by a comma.
