IfThisThenThat should be the next big thing on the social web. It's bloody brilliant.

Here's my description for non-technical friend: IfThisThenThat lets all your online stuff work together to do way more interesting stuff. It's the magic of OAuth and the proliferation of nice, clean public APIs that makes this possible.
