I guess that would be why its free for .Mac, its made to work solely with .Mac.
Pamela - To answer you're question on your "blog", blogging comes from the action of making a blog. Blog comes from the shortening and evolution of the term "web log" which is a log on the web that usually catalogues the changes of an application, a way to inform readers of new news, or posting articles to a web site to be viewed. However blogs, are almost always geared to a topic, and that topic is never, "this is my blog where I moan and complain about my life and say my pet is so cute when I tie it in a knot".
That is a journal, many, many, many people get that confused. A journal is similar to a blog, but is more of a blog diary, so in essence and definition it may fit blog, but its more of a public diary where people share what happened to them. LiveJournal is a great example of a website devoted to such things. Personally I run a JournaBlog, (I made up the term as far as I know), as its half journal since it contains some personal things most people wouldn't care about along with some pertinent info that actually describes on something I'm working on, or as seen in jfpoole's blog, where I compared a Dell and a Mac, and came up with a Dell $1000 more expensive.
The only actual blog I run is the ehMac Gadgets blog, which I just finished redesigning, and the link will be made available when ehMac Place is opened. ehMac Place is my fancy name for the website I'm creating detailing the ehMac Gadgets, and accompanying blog.
