The survey found men and women have statistical parity in blogosphere, with men representing 54 percent of bloggers and women 46 percent. Susannah Fox, the Internet project’s associate director, said the attention devoted to bloggers has focused on ‘‘a small number of high-traffic, A-list bloggers.’’ By asking a wide range of bloggers what they do and why they do it, ‘‘we have found a different kind of story about the power of the Net to encourage creativity and community among all kinds of surfers,’’ she said. —Nick Madigan
