If you use a Mac, and if you blog, I recommend checking out Red Sweater’s blogging app MarsEdit. It’s a great blogging tool that uses several modern blogging services and allows you to blog on your Mac instead of online. One of my favorite things is that it ties in with Flickr to seamlessly add images to your posts. Get a 30-day trial to make sure you dig it.
Also be sure to check out Daniel’s blog for great reading about marketing, Mac software, and other cool stuff.
