The New York Review of Books, highbrow home of Joan Didion letters and occasional epic literary feuds (or "nerd fights") today undertakes it greatest challenge: explaining "blogs" to its million-year-old readers. The author assigned to the task? Journo (and cartoonist!) Sarah Boxer, who has assembled a little print anthology of blog "writing." Which means that her task is two-fold, actually: explaining blogs to old people and justifying collecting them into a book to herself. How does she fare? Hilariously!
