I don't understand why people take such a cynical attitude towards new things.

If you bothered to think or look around a bit, you would notice that some people are already using ifttt for things, which a lot of people might find useful, such as tracking jobs, apartments and flights. (http://news.ycombinator.com/item?id=2970550).

If you have no use for something, why blog about it with an undertone implying it has no use for anyone?

Maybe it's not your intention, but this just comes across as taking the mickey out of people's creations just for the heck of it. Just because you've got a blog.

Sometimes, it's best not to say anything. Enjoy the silence while it lasts.
