Blog genres

In regards to the genres of blogs, you could easily say there ought to be one for every kind of person you could think of.

In a somewhat easier, more discriminating categorization, I see these "genres":
Professional blogs (Political, Work... anything that ties your "character" into an established role)
Personal blogs (The counter-part of the professional blog)
Blogs part of a "context" (When the blog is used as an intermediary, ex. as part of art, or when it is self-reflective)

A blog is most definitely a remediation or recreation of traditional literary genres, and so it becomes heavily laden with preconceptions from traditional print culture, therefore taking with it many of the subgenres and stylistics found in print. My "taxonomy" of these blogs is in regards to what role the "author" has, not the stylistic approach or based on their informational matter.

I personally don't follow any blog, except perhaps feber.se which is much more of a blog-shaped news site. As a literary phenomenon I see blogs as an interesting thing, but I can't help but feel dually uninterested since the more common, non-artsy, non-academic blog, is all too often centred on topics so personal that they become almost inaccessible to anyone outside the span of the author/blogger.
