For as long as I've had a Twitter account, I've had it set so that my tweets automatically went to my Facebook account, as well. Now, it no longer works. Twitter sent me (and I assume everyone else) instructions on how to fix this. These instructions don't work. Step 3 is the problem (so far). "Click Connect to Facebook." There is no option on the settings/application page that reads "Connect to Facebook." There is "Facebook Connect," but it's not clickable. Lincoln
They disabled this feature. Probably for the best. In my opinion its better to not have your social content linked.
There's probably an IFTT function to do it if you want to. I find that I post very different things on the two sites and have a very different audience. The brief time I had them linked many years ago got my fb friends all grumpy.
