This is a step in the right direction. WP.com should move away from the strictly social networking agenda they have now and get more professional. At least they should have such an option. If you look at what Squidoo has done from ground up, you'll notice that their business model is perfectly suitable for WP.com , with so many existing users. Wonder why WP.com did not consider revenue sharing with publishers earlier, Is it the Tumblr factor?
