How do I add a "Blogs I Follow" widget to a WordPress.org site?

Hi,

I am in the process of moving a site from WordPress.com to being self-hosted.

One thing I liked about WordPress.com was my ability to follow other blogs and have people follow my blog. Is this still possible with self-hosted WordPress.org?

Also, on WordPress.com there is a widget called “Blogs I Follow” – is there some way to achieve the same thing with WordPress.org?

Thanks for any pointers!
