Comma, Comma, Comma, Comma, Comma Chameleon

I complained before about Jane Austen’s generous use of commas at the start of Sense & Sensibility, but she’s really outdone herself at the start of Persuasion. There are twelve commas in the first sentence alone.
Not to mention a colon, three semi-colons, and two dashes. I’ll be generous and not include the commas in the citation that completes the sentence since some of the commas are associated with dates.

I’m not sure that such wanton use of punctuation caused global warming, but it can’t have helped.
