I am a big fan of Digg despite its lefty leanings. They've been promoting a browser called Flock which integrates a lot of the features of social networking sites in to the browser itself. Part of this functionality is the blog post capabilities I am checking out now.
I had some problems getting the plug in to work by logging in to my blog provider, but after going through a manual setup it seems to be working adequately now. It's got a nice editor with full functionality. I think this Flock thing is growing on me.
