As the weblog buzz grows, more and more people are starting blogs. Most people want to start with a free blog as a low-risk experiment - which normally means Google's Blogger. There are a few great alternatives, though, particularly Microsoft's MSN Spaces.
The Wall Street Journal's Walter Mossberg recently compared the various alternatives and chose MSN Spaces as the best, easiest choice. His article is definitely worth checking out if you're about to make the leap!
One warning: starting with a free site makes perfect sense, but if you do choose to move your blog to another service down the road, the transition can be painful.
