I believe the term "blog" means more than an online journal. I believe a blog is a conversation. People go to blogs to read AND write, not just consume.
I interviewed most of the presidential candidates about their positions on technology issues in the 2008 election. After those interviews I endorsed one candidate from each party - Barack Obama and John McCain. Neither of them were leading the primaries at the time, but they seemed like the best candidates, solely from a tech policy perspective.
