Julie Leung just gave a very powerful talk about the social and personal aspects of blogging. I haven't read her blog before, but now I'm very much looking forward to digging in.
One of the real poignant things that came to me while watching her presentation is the dichotomy between the cold, technical side of computers and technology and the warm, aesthetic things that are possible with this technology. Blogs to me are like grass growing through cracks in the concrete. It's the deep human need for expression coming through in everything humans do.
