Hello blogging friends!
And once you click on that link, a new page will open in your Browser which will have the Feedburner Logo at the top, and this is where you type in your EMail address as well as some text in a little box to prevent SPAM. You should then receive an EMail from Feedburner which will contain a link which you must click on to activate your subscription. Please check your SPAM EMail Inbox if you have trouble finding the email. If you don't activate your subscription by clicking on the link, you will NOT receive email updates. You will not receive SPAM from Feedburner by subscribing; it is merely a tool for Bloggers to connect with their viewers.
Or if you want so subscribe in a different Reader (other than Google), you can click on the Subscribe now in a different Reader box and choose your preferred feeder eg: Yahoo, Netvibes etc. (although I did notice when I clicked on it that you can subscribe to Google in this selection anyway).
