Most feed readers default to a long list of headlines and articles with a folder-like navigation tree on the left to help you sift through your feeds and unread posts. It works, but FeedSquares is a Chrome extension that connects to Google Reader and uses tiles to display your feeds instead. Highlighted and off-axis tiles indicate new topics, and you can click any tile to see the posts for that feed and any article to bring up the full text.
Once installed, click any tile to bring up the list of articles from that feed in a horizontal list at the bottom of the screen. When you find an article you'd like to read, click it to bring up the full text and click anywhere off of it to minimise it again. Folders you've created are displayed as menus at the top of the screen and clicking one rearranges the tiles so you only see the feeds in that folder.
FeedSquares isn't necessarily faster than other tools: it takes several clicks to get from the base display down to a new article, more than other, traditional feed readers. What it does differently -- and well -- is give you an easy way to see where there are new and unread articles to read, browse through your feeds without obscuring the feed list and offering a fun and different way of interacting with your RSS feeds. If the inbox-look is tired to you and you wish there were another way to read the news, FeedSquares is worth a try.
