Just a quick note to state this as a fact, in case anybody was wondering (and since I’ve had a few emails about it lately).
Under no circumstances will I ever implement Facebook’s “frictionless sharing” in Simple Facebook Connect. If you want such a thing, I recommend using another plugin.
Facebook’s frictionless sharing is a privacy invading, oversharing, useless-result creating nightmare. I block websites that use it from appearing in my News Feed, I remove Applications and services that implement it (hey Yahoo!, you’ve been axed from my life entirely because of your use of this crap), and I will not help anybody to implement it or even provide them with useful advice.
In my opinion, this is by far the worst thing Facebook has ever created. Even if you ignore the privacy implications entirely, Facebook has finally succeeded at doing something that they have been trying to do for ages: Make Facebook’s main feed almost completely worthless.
I will continue to add other features to SFC, but I use FB a lot less than I did before (and am now focusing more on Google+ anyway). However, this is one “feature” that I will not be adding.
Oh, and I’m not the only one who thinks this idea sucks rocks, BTW.
