Ifttt is one of the best things I wish I could pay for. It's excellent at plugging holes in my various systems. For example, I now rely on Fever Reader for RSS. While it's comforting that I now own my favorited articles, I also wanted them in my Pinboard.in collection. IFTTT solves this by scraping the RSS feed of my Fever installation and adding the links to Pinboard.
I also have an IFTTT rule for adding any links I post to Twitter.
