The founder of Instapundit is Glenn Reynolds, a law professor at the University of Tennessee who came to be known as the "blogfather" to many of us then toiling on the border between print and pixels. His new book is called The Social Media Upheaval. In it, he makes the case that the federal government should use antitrust law to curtail the cultural, market, and political power amassed by Twitter, Facebook, Google, and other tech companies.
