In simple terms, a blog is a website, 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 are pretty sure that the whole deal is just getting started.
