Emma over at Notes On the Atrocities analyzes the prose of various blogs. First there is the "ur-blog/news-digest model"--efficiency and economy--think Atrios:

Atrios is to blogging what haiku is to poetry--economy and efficiency...The style accentuates immediacy....It’s quick and pithy. The speed of news and communication is palpable on Eschaton, and he treats his readers with a prose style that underscores this ethos.

Then there are the essayist blogs. Go read which ones Emma selects to dissect. And then there are the activist blogs. Emma says TalkLeft, like Tom Tomorrow, is an activist blog.

Tom and Jeralyn might make some changes if their blogs were going into the New Yorker. But that’s not really the point. Their directness and candor speak volumes. The posts are more like personal emails mailed out to friends than official publications. We understand that it’s more important for the posts to get posted than it is for them to be posted error-free.

Thanks, Emma!
