Yesterday’s BloggerCon felt at times like a revival meeting, preaching blogs as the Internet’s second coming, if not humanity’s salvation. Yet I could not escape the irony of the place. Amid fiery talk of blogs cracking the matrix, of blogs as the second superpower, of blogs breaking down social, political and cultural barriers, the temple in which we worshipped was none other than Harvard Law School — that most steadfast bulwark of established law and old-school power. Even lunch was in a room named Ropes & Gray, Boston’s whitest-shoe law firm.
