Microsoft is trying to googlize itself by competing with the various Google apps (Just as Google is doing the same with Microsoft applications). They've rolled out their Windows Live service with a bunch of features.
I haven't been able to try them all, but the most impressive one is Windows Live Writer.
I've been using Googles Blogger/Blogspot for my blogs. It's good, but I've had problems with formatting. When start a new paragraph, I want a new paragraph, and Blogger seems to mash them together when you add a graphic. I also don't care for the fact that when you add a graphic, it's always at the top of the post and wrecks havoc with the paragraphing.
Microsoft's Live Writer is desktop blog writing software. It works like a word processor, but takes into account how blogs work. You write your entry and then publish it to your blog, and yes, it works with Blogger/Blogspot.
There are also other features. I haven't tested them out yet, though the mail looks interesting. But you may want to check out Live Writer at the Windows Live website.
