Free plan and a $200/mo plan. Considering I used to pay a friend $10 to do this every time I made a post or two on a niche site... its well worth the price of free, and possibly $200 if you're a serious blogger with a few million applications to update each time you post. Its also a white hat SEO technique. You're basically backlinking to yourself, but doing it for the benefit of the social masses, etc.
