I spent the better part of the evening reading up on the Facebook Graph API and writing a tool that can do my auto-posting for me. Right now it only works with Facebook. It can post images, status updates, and links in their native format. It’s not too smart about interpreting which of those formats it should use. Also, it’s comically inept at getting an authentication token. Long-lived tokens last about 60 days, so I have a while to fix it.
If you see this, and it says that it was posted by “Emposter,” then it works.
