Blogging is about more than just putting your thoughts on the web. It's about connecting with and hearing from anyone who reads your work. With Blogger, you control who can read and write to your blog — let just a few friends or the entire world see what you have to say!
Blogger Comments let anyone, anywhere, offer feedback on your posts. You can choose whether you want to allow comments on a post-by-post basis, and you can delete comments you don't like.
Access Controls let you decide who can read and who can write to your blog. You can use a group blog with multiple authors as a communication tool for small teams, families and other groups. As a single author, you can create a private online space for collecting news, links, and ideas, to keep to yourself or share with as many readers as you want.
