Create a new folder in Google Reader
It’s an easy task. Go to the Reader Settings menu by opening the gears icon on the top-right hand side of the screen. Then, select the Subscriptions sub-menu.
There, you’ll see a list of all your feeds. To make a new folder, select the drop-down box next to one and select, “New Folder”.
Once you’ve done that, you’ll be able to select feeds to drag them into new folders.
