It's one of 70 million of them. I chose Blogger for no other reason than I've heard of it, and it's free. Sorry TypePad. In the realm of social software (blogs, wikis, whatever you call sites like yedda) there are a lot of options, and I frankly do not have the time right now to research and compare them. Blogger/Blogspot seems to work for Mark Crofton at The Village View, Frank Scavo at The Enteprirse System Spectator, and other blogs which I frequently read, so I imagine it will work for me.
Mid post I took a peek at a recent entry on another of my favorite blogs, Procurement Central, and I see that Wordpress is also free.
Ok. Just shut up already. This is less about the tool and more about sharing what's in my head, should someone stumble across it and find it interesting.
