Now WordPress.com brings another feature to its users. This time, they are bringing in a third party tool made by Google to enhance user experience over wordpress.com blogs.
To enable this, go to your admin area or dash board and click on the turbo link on right top corner. A window will appear and it’ll ask you to install gears in your browser. Just accept it and install it to improve your browsing experience.
PS: Images, files will be locally Cached in your machine, so don’t use this feature in shared machine, because others can easily gain access to your sensitive materials.
