It's certainly easy to open a blog with Blogger, but I had some trouble making mine look the way I wanted. Too many things, I found, were locked down behind the Template Designer interface. For example, I didn't want the background gradients at the edge of the text area that came with the first 'Simple' template, and it took several minutes to realise I was supposed to express this by choosing a different template.
Neither did Template Designer give me control over the text size, or font properties other than colour, to apply to the blog description. It didn't give me control over the text size to apply to date headers. And I couldn't have my blog title appear in capitals (which seemed important). On the other hand, you're free to edit the HTML template, where I could do these things.
