If there’s one thing we’ve learned about the web, it’s that people really like to like things. That’s why the latest version of Jetpack introduces a “Like” feature. The new feature enables a “Like” area at the bottom of your posts and pages. A button allows your readers to show appreciation for your posts as well as save your posts for later viewing on WordPress.com using the Reader.
Once a user likes your post, their Gravatar will be displayed below your content, allowing you to engage with them further. You’ll also receive a notification in your toolbar if you have the notifications module enabled, and an email notifying you of the action.
Likes isn’t the only new feature in this release. We’ve also added a Readmill widget, a bulk spam feature to the contact form, improved our Pinterest share button integration, and a slew of bug fixes.
For a complete list of changes, see the changelog.
