They’re not personal blogs. They’re not generalist blogs. Oh, hell, I read enough of ‘em — I guess they’re Historical Blogs. Thus, Bostonia (original), a lovely little series of explorations of Boston’s rich history; Old is the New New, “with a special interest in the history of technology and business in America and the world”; Cliopatria (original), a lot of smart people talking about history together; and Pillow Talk, a blogaptation of Sei Shonagon’s “Pillow Book.”
(“Blogaptation”: my entry in the ongoing contest for the most painful neologism involving the word “weblog.” But really, it’s hard to beat the original “blog,” isn’t it?)
