We do not literally mean Tiles on Floor when we say "Read your feeds on tiles"! We are talking about Feedsquares - a Google Chrome add-on that provides a new dimension to Google Reader when viewed in Chrome Browser. This add-on arranges all your feeds in tiles and makes it easy for you to browse your Google Reader feeds.
Feedsquare is a Google Chrome Add-on that shows your Google Reader feeds in a beautiful tiled feed wall along with image previews as you can see in the image above. It also lets you synchronize read status/stars/tags with Google Reader and lets you share articles to Google Buzz, Twitter and Facebook.
For more details, you can go through this tutorial. You have to be logged into your Google Reader account in order to use this add-on.
