So many of us blog. That's the fun of it. Your Uncle Fritz writes a blog about scrimshaw. Your kid's teacher writes a blog about elementary education. Your book club writes a group blog about, well, books. And these heavy duty thinkers write blogs that explore a world beyond their books, lectures and performances:
Lawrence Lessig writes about the culture of the internet and cyberspace law
Edward Tufte has been described as the "Leonardo da Vinci of data" (not a traditional blog, per se, but very much his own approach)
Richard Edelman founded of one of the world's largest PR firms
Musical innovator Moby is also a writer and activist.
