Posting online for Mac bloggers

I have recently purchased a Powerbook computer. I travel quiet frequently but need to get a blog up and running. I have been researching the alternatives for Mac blog software. There many packages to choose from.  A friend recommended that I use consumer reviews as a way to sort through the available options. I will use these to establish the guidelines and then download a free trial. This has worked for me in the past when I needed to work out which software to purchase.
