Blogger

The name itself is already pointing out what Blogger is meant for. This product's focus is on blogging, and not on social networking or complex website development.

The simplicity of design and ease of use in general, are the main reasons why Blogger is the favorite platform for most people who want to start blogging. It is free and you can easily log in with your Google account. It is a fully-hosted blog platform, and the speed and security are provided by Google, so all that's left for you is to focus on your content and on promoting it.
