Number 1 blogging site?

I believe a lot of people would go with Wordpress. However blogger.com is great too. Wordpress has great SEO built-in and Google loves it, so if you want your blogs to get picked up and indexed in Google, go with Wordpress.

Hope this helps.

Blogspot isn't that bad...

It also depends on what kind of blogging you want to do. Some sites are tailored for specific needs. Poetry, journalism, math/science. What exactly do you mean by "The Best"

We use blogger mostly due to fact that Google bot looks there first before logging on external sites. www.blogger.com (http://www.blogger.com)
