Double-posting
Sorry about the double-posting you've been seeing from me on my Twitter. Turns out my IFTTT connections were firing two different recipes.
I linked my Wordpress to my FB Page, and told it if I had a post tagged with "Image", to upload the image to the page (which would also add the post to the image description). If I had a post tagged with "NoImage", to post a status message instead.
Turns out IFTTT put my blog entry as a status message AND uploaded the image, which fired two FB Pages recipes. One for tweeting a status message, and one for tweeting an image.
So instead, I've just set my Wordpress connection to only ever put a FB Pages status message, and stopped using the Image/NoImage tags.
