So, apparently as of today, Facebook eliminated support for third-party share buttons, at least in such a way as was being used by this site. For the moment, I have deactivated share functionality on the blog, and am searching for a new way to reintegrate Facebook with this site. If anyone out there is familiar with how to do this, please shoot me a tweet or an email.
I apologize for the inconvenience.
Update: Okay, so it turns out that I was using the old “Share” button and that Facebook is forcing us to transition to the unrolled “Like” button that was released awhile back. I hadn’t wanted to switch because liking eliminates the ability to make a comment on your FB page as you share it with friends but… well… it’s impossible to use the “Share” button now so we’re all stuck with “Like”.
I’ve replaced the existing social media options on the blog with Sociable, which has Facebook, Twitter and G+. Please let me know if you want me to add any other sharing options to the site; I’m happy to do it. Please let me know if you have any problems getting anything to work. I’ve tested both the Facebook and Twitter buttons, and they seem to be functional.
