Semicolon revisited

In an earlier post, I dissed the use of semicolons, based on the opinion of the late, great Kurt Vonnegut. Even Vonnegut, however, flagrantly used a semicolon in the same book where he decried the use of the said punctuation. So I feel I too must be fair and balanced. One of my heroines in the field of language is Erin McKean, who has established the Semicolon Appreciation Society, which I have to support if for no other reason than its similarity to The International Association of Turtles.
