Google Chrome OS will have three default fonts. Tinos, Arimo and Cousine. You can download them from this URL. Unzip the folder and copy those fonts to control panel > fonts folder in windows.
Now, go to Google Chrome browser options, and select font settings. Change font settings as shown in the screenshot above.
Reload, and you are good ! Feedly takes this default font and gives all the blogs you follow in an awesome format, with Google Chrome OS font set.
