"To my parents, Ayn Rand and God" is a classic, and thus has been countered with "To my mother, Ayn Rand, and God".
"Here lies Charlie Weeks, a lawyer and an honest man," is a bad example, because of the singular verb. The most obvious interpretation rules out a series before we even get to the comma. On the other hand, I doubt that "Here lie Charlie Weeks, a lawyer and an honest man," would be too ambiguous.
The
link's main example is flawed, too:
The author presents the following sentence as confusing on account of the serial comma:
link said:
The above information comes from the Australian Antarctic Division site: http://www.aad.gov.au/ which has details of many things relating to Antarctica, including the scientific bases at Heard Island, Mawson, Davis, Casey and protecting wildlife.
And then says that the serial comma avoids the confusion:
link said:
The above information comes from the Australian Antarctic Division site: http://www.aad.gov.au/ which has details of many things relating to Antarctica, including the scientific bases at Heard Island, Mawson, Davis, Casey, and protecting wildlife.
Because:
link said:
Aah - suddenly it makes perfect sense. The site has details of the bases, plus information on protecting wildlife - there's not a base called, "protecting wildlife."
But that's not true. The list is awkward with or without the comma. Whether you use the comma or not is a matter of taste, here.
See: the core sentence could be phrased like this:
The above information comes from the Australian Antarctic Division site: http://www.aad.gov.au/ which has details of many things relating to Antarctica, including various scientific bases and protecting wildlife.
So what we have here is a list of two items separated by an "and". Not even the most ardent admirers of the serial comma would use one here.
The problem comes because there's a second, longer list embedded in the list of two, but it's not finished off with "and":
the scientific bases at Heard Island, Mawson, Davis, Casey
would read more natural as:
the scientific bases at Heard Island, Mawson, Davis(,) and Casey
Now how do we re-introduce this into the sentence?
a)
No serial comma: The above information comes from the Australian Antarctic Division site: http://www.aad.gov.au/ which has details of many things relating to Antarctica, including the scientific bases at Heard Island, Mawson, Davis and Casey and protecting wildlife.
b) Serial comma only in longer list: The above information comes from the Australian Antarctic Division site: http://www.aad.gov.au/ which has details of many things relating to Antarctica, including the scientific bases at Heard Island, Mawson, Davis, and Casey and protecting wildlife.
c) Serial comma in both lists, making an exception for the no-comma-with-two-list-items rule: The above information comes from the Australian Antarctic Division site: http://www.aad.gov.au/ which has details of many things relating to Antarctica, including the scientific bases at Heard Island, Mawson, Davis, and Casey, and protecting wildlife.
Although if separate items in a list that themselves contain commas, you use the semicolon, so c) might also look like this:
The above information comes from the Australian Antarctic Division site: http://www.aad.gov.au/ which has details of many things relating to Antarctica, including the scientific bases at Heard Island, Mawson, Davis, and Casey; and protecting wildlife.
d)
(No) Serial comma in only the extended list, but setting the extended list off as a parenthetical phrase (using commas would add confusion, so I'm opting for dashes - brackets would be an alternative):
The above information comes from the Australian Antarctic Division site: http://www.aad.gov.au/ which has details of many things relating to Antarctica, including various scientific bases -- at Heard Island, Mawson, Davis(,) and Casey -- and protecting wildlife.
Personally, I think the best solution (with or without the serial comma doesn't matter at all) would be to simply reverse the list items (and rephrase "protecting wildlife", so you don't get "including protecting"):
The above information comes from the Australian Antarctic Division site: http://www.aad.gov.au/ which has details of many things relating to Antarctica, including wildlife protection and the scientific bases at Heard Island, Mawson, Davis(,) and Casey.
I do think this site isn't accurate enough about the issue at hand, and - in its main case - was scape goating the serial comma's absence. I also think it's a case of rule-blindness (which I know because I've suffered from this myself more than once).
Seriously: use the serial comma or don't. Most readers won't even notice on which side you are.
