About 3 years ago we started the process of shutting down NetworkedBlogs. We tried to do it gradually and very slowly to give everyone enough time to transition to other solutions. Initially, we stopped accepting new user signups, and then over time stopped most other features. The syndication feature is the last one remaining and we'll be stopping it on June 6th.
As a refresher, syndication is the feature that automatically shares your blog posts to Facebook and Twitter. The shutdown won't affect your blog itself, which is likely hosted on Blogspot, Wordpress, Tumblr, or other blogging platforms. These services are NOT affected.
After the syndication feature stops, you'll need to manually share your new blog posts to Facebook and Twitter rather than having NetworkedBlogs do it for you automatically. Or you might want to consider using a different tool. I'm including a few suggestions in the link below.

We've had the pleasure of offering this service to you over many years, and we hope we offered something useful. If you have any questions, don't hesitate to reach out to us.
