Exactly; I don't use it either, but there's a phenomenal number of "solve problem X" how-tos that start with "If you don't have an IFTTT account, sign up now. It's free!"

Thus, I am predicting that at some point in the future, the community will tip over into backlash. Much the same as it does for other "free as in SaaS" services. It just sort of mystifies me that we haven't reached that point yet. IMHO, that reaction seems overdue -- IFTTT is as widespread as (e.g.) DropBox and Thingiverse were when the "hey this isn't Free" tipping point hit. Puzzling that it still hasn't occurred.
