Thanks to the Publicize module, you can automatically publish each one of your blog posts to your Path profile.
To get started, go to the Settings -> Sharing, then click the Add New button next to the Path logo.
You’ll be taken to Path where you’ll be asked to approve the connection between your WordPress.com blog and your Path account. Click Allow.
You can also make the connection available to all users of the blog. Meaning that when another user creates a post it will also publicize to this Path connection.
