I did get Facebook Auto Publish plugin working (setting up the Facebook app was new to me too and I was amazed when it did worked!) but I soon turned it off again. Two main reasons. First I’m not very good leaving my posts alone. I’d go in an edit one and it would automatically get published to Facebook again. So I’d have to go into Facebook and delete it. Secondly I have a Social Media plugin which adds share icons for Facebook and Twitter to my website. It’s quick and easy to use this myself to publish a post to Facebook and means I can add a sentence or two with whatever I want to say (e.g. Blog Alert!), hashtags etc.
