OK, I'm really behind the times. I just discovered ScribeFire, an add-on to Firefox that allows you to post directly to your blog. I'm using BlogEngine.Net, which supports MetaWeblog API. Scribefire interfaces directly to this API. Scribefire and BlogEngine.Net also support RSD (Really Simple Discovery), which assists in automagically interfacing with your blog. All you need is a log in and a password. That's it for now. I need to figure out what I can do with Scribefire.
