Show a pop-up business card of your users' gravatar profiles in comments.
A Gravatar is your profile on the web, and the Hovercard is one way your information is made visible to others. It’s an easy way to help people find your blog, or access your identity on other services like Twitter, Facebook, or Linkedin.
Hovercards appear when you place your mouse over any Gravatar. Go to Settings > Discussions in your Dashboard, and scroll down to the “Gravatar Hovercards” section. You will see a sample of your Hovercard.
Jetpack is a plugin that ships with many modules. Why install the whole package, if you're just interested in one module?!
This plugin is the exact Gravatar Hovercards module of the original Jetpack plugin, only without all the extra stuff.
The version number of this plugin will follow the version number of Jetpack. This way, it's easier for you to know which Jetpack version this module was extracted from.
Things you'd be happy to know:
Note: Translations was not included, due to the fact that Jetpack uses one transaltion file for all the modules, which makes it really difficult to extract translations. The good news is that the module can be translated easily.
