We have developed an extension for one of our sites and decided that it might be useful for many. Popular news agencies order development of such extensions spending a lot of money on it. Many bloggers cannot afford it.
With our product you can allow users to instantly receive the latest news of your site. Also your extension will be placed in the Chrome Store directory, which has an audience of more than 200 million users. It will help you to reach new customers.
