I am part of the Jetpack team developing Jetpack Social and I want to give props to the author of this post. You did a great job describing what is going on with the product.

I also want to clarify some points based on the comments. Jetpack Social is focused on auto-sharing your site content to social media. The social sharing buttons that are part of Jetpack aren’t part of Jetpack Social at this time. So readers of your posts can continue to share your content to social media as much as they’d like. There is no limit on that.
Likewise, there is no limit on the number of social accounts you can connect to or the number of users that can use those connections. You can set it to automatically post an image and excerpt from your blog post on the social media platforms you choose on the schedule you choose.

Jetpack Social is available within the Jetpack plugin or as a standalone plugin. The standalone plugin doesn’t include any other Jetpack features. So if you’re not interested in Jetpack’s security or performance features, you can use the Jetpack Social plugin by itself.

As mentioned in the post, we’re working on some new features like the social image generator, additional social platforms, organic social posting that makes the post look native to the platform, video sharing, and more. To keep up with what’s coming next, you can follow us on Facebook and Twitter.

My team is committed to bringing the social features you need to your WordPress dashboard and we’d love to hear from you. You can sign up for a user research interview here.
