If not, you should! It makes blurfing (love that Alison -- it means Blog Surfing) so much easier!
And then, once you have all your favourite blogs saved into Google Reader, you should enhance your experience with the "next" button that can be installed in your bookmarks toolbar.
do you know about the Next Button you can use with Google Reader? It goes in your bookmark folder (or the bookmark bar on the top of your screen) and you click on it and it will take you to the next unread page... keeps going until you've been through all your blogs. I like it cuz it takes you to the actual webpage...
To do it....
*Go to Google Reader
*click on settings
*click on goodies
*find "put reader in a bookmark"
*drag the highlighted "next" to your bookmark bar (the bar at the top if you're using Mozilla or Firefox)
***If you are using Internet Explorer, you need to first click on View, then on Explorer Bar and then choose Favourites. A section on the left side of your screen will open up with all of your Favourites (bookmarks). Click and drag that Next button to that area. If you leave this Favourites bar open all the time, you'll lose a little screen space but will have all of your bookmarks easily clickable
This saves you a little time and effort.... instead of just a portion of a new post, you will be taken to the actual page of the blog and you'll easily be able to see any photos and scans and read the entire post... or simply hit "next" to head on to the next new page!
