Add Blog Comments to Google Reader
Step 1: First you need to find the blog's complete feed URL. Usually that is the same as it's regular URL plus a few extra words, but always double check. To do that, click on the blog within Reader
FEED SETTINGS: View Detals and Specifics
Step 2: Copy the URL for the feed and click the big red SUBSCRIBE button. Paste the URL into the box, but change the word POSTS to be COMMENTS. The feed will be added to the Blogs I'm Following folder, you may want to rename it so you can tell it is comments, instead of the regular feed.
For this blog the comments URL http://www.androidmom.com/feeds/comments/default
Add a Blog to Google Reader
There are two easy ways to use Google Reader to read blogs, in case you need help with that first step.
1.) If the blog you are reading has a Google Friend Connect button, join it. Then log into http://reader.google.com and all new posts are automatically added under "Blogs I'm Following". You can reorganize them into groups that make more sense to you.
I also set my FEED SETTING to show on NEW ITEMS, as opposed to ALL ITEMS. But the great thing is that when I need to search all the blogs I follow, it will search all of them and the unread posts will be highlighted. Searching through all the blog is just one of the really great advantages of using Google Reader! I know I read about a recipe, but can't remember who posted it, so I just search for "Eggplant" and it will list all the posts I subsribe to with Eggplant mentioned. How great is that?
