We just recently launched our latest extension: Facebook Like Button. When Facebook announced this new way of connecting with users on Wednesday, we immediately got to work on making it easy for you to add this powerful feature to your Magento catalog.
Our goal was to make it so that you can add a Like button to your catalog in less than 5 minutes. If you've got 15 minutes, you can take the time to set up a Facebook application and enable the commenting feature of the Like button - something that we highly recommend.
You can see a sample of the commenting feature here. The 5-minute install version is here.
One last note: In addition to adding a Like button to your product pages, we optimized the experience for your users by adding meta tags with the most relevant product name, image, and description and providing a central place in the Magento admin for managing your buttons.
