I don't blog - but I wouldn't completely discount a blogging service off the bat. It depends on your purpose and if you have an established audience.
The key to a lot of those services is that people can easily find you and you can network with other blogs, thus increasing your readership fairly rapidly.
Where as with a stand-alone site, if you don't already have a flowing you need to focus on advertising and really getting you name out there (so to speak).
My personal website used to be where I stored photo's, wrote about my life and kept updates on what was new. Only my closest friends and family would check it - and only on an irregular basis. But now, between sites like flickr, twitters, facebook etc, my personal site is all but obsolete but I'm more connected with people then ever.
Just a thought.
