Linkable plugin
Allows you to easily create posts that link to remote URLs, Daring Fireball style.
The plugin adds a a new metadata key ('url') that you can set on each
page in order to specify the URL for the remote article. Nesta's
url_for
helper will resolve to the remote URL for easy linking in link
posts and in your Atom feed.
