I've been playing with iBlog. I'd send you over to it to see the results but I can't figure out what the URL is of the test blogs I've created on my .Mac account. Funny, no? Spent 20 minutes looking through help and trying various tests with no luck. Other than this small detail, which I'm sure some kind reader will see me through,it's a pretty nice desktop (Mac) client for both reading and writing blogs.

UPDATE: If you change the name of your blog from the default, then it's published to an address like http://homepage.mac.com/mkapor/iblog/B976004395/index.html. This is mine, but it's currently empty. That is, it assigns a random string as part of the address. Not the best design choice IMHO. When you use iBlog to publish, you have to remember to put a checkmark in front of the blog name or it won't do anything. Not sure why they made this the default.
