What's a blog?

A blog is  A daily pulpit. A collaborative space. A breaking-news outlet. A collection of links. Your own private thoughts. Memos to the world.
Your blog is whatever you want it to be. There are millions of them, in all shapes and sizes, and there are no real rules.
In simple terms, a blog is a web site, where you write stuff on an ongoing basis. New stuff shows up at the top, so your visitors can read what's new. Then they comment on it or link to it or email you. Or not.
Since Blogger was launched in 1999, blogs have reshaped the web, impacted politics, shaken up journalism, and enabled millions of people to have a voice and connect with others.
And we're pretty sure the whole deal is just getting started.
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 any 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 an excellent communication tool for small teams, families and other groups. Or 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.
Blogger Profiles let you find people and blogs that share your interests. Your Blogger Profile, where you can list your blogs, your interests, and more, lets people find you (but only if you want to be found).
