WordPress.com has introduced two new features to their blog service: a like button and reflagging. The new features can be accessed through a Like menu item in the admin bar at the top of WordPress.com pages.
The author can find out how many times people have clicked the like button on their post. Once you click like on a blog post, the top menu says “you like this.” In that same menu there is another option that says “Reblog this Post.”
If you click Reblog this Post, it takes you to QuickPress. QuickPress contains the title and the beginning of the post you are reblogging. The reblogging feature is very similar to what Tumblr and Posterous offers.
