I've been using IFTTT since it came out ages ago, and it's one of the first things I install on any new phone. I use it as the connective tissue for all my smart home products and apps. You can do amazing things with it.
Support is non existent along with technical user information.
I have used it extensively in Andrew Chen's talk platform: http://talk.andrewchen.co/ and also for Write The Docs forum at http://forum.writethedocs.org/. I think it meets most of the goals of a well structured, well monitored, and custom discussion forum. I like it.
