Dumb question: isn't IFTTT one of the companies that HN always cautions against building (one dependent on the availability of others' sites/APIs)? Or does that only apply for sites dependent on 1 other service?

Well, they don't rely on a single API, though. They've implemented dozens of API's. They also have some of their own API's, as well.

If it were a case of relying on 1 or 2 mission-critical API's then I'd be worried.
