What blogs reveal?

What blogs reveal about one is a deeply technical or deeply philosophical question. They have attracted a lot of interest academically. In computer science, people have abstracted problems based on text attributes, analogies with epidemiology on the spread of "memes" through blogs, studied graph properties and so on. In doing such study, one becomes quite familiar with the literature from people in CS and related fields, but also start to learn how they are approached by other fields such as sociology and psychology. An example is a study on gender, identity and language in teenage blogs, done a couple of years ago. A long (exhaustive?) list of blog related research from all discplines appears on the homepage of a blogging researcher / researching blogger.
