When you follow a blog on WordPress.com, the new posts from that site will appear in your Reader, where you can view the latest posts published across the blogs you follow. You’ll also receive notifications of new posts by email.
How to Follow Blogs
If you have a WordPress.com account, when you are logged in, click the Follow button that appears in the bottom right-hand corner of all WordPress.com sites:
All new posts published on that blog will now show up in your Reader. You will also receive email notifications of new posts. You can change your settings to Immediate, Daily, or Weekly delivery, or opt-out of email notifications.
If you do not have a WordPress.com account
After clicking on the Follow button, a dialog box will pop up asking for the email address where new blog posts should be sent.
Be sure to click on the confirmation link in the email that we send you. Until you’ve confirmed your subscription request, you won’t receive email notifications for new posts and updates.
Note: Blog administrators can hide this Follow button by adjusting their email reading settings. Here they can also customize the message that’s sent when someone follows the blog.
You can also follow a blog using the Follow Blog Widget in a site’s sidebar:
