IFTTT, a very simple web tool that might end up becoming indispensable, has just opened to the public, with some new features in tow. IFTTT stands for "if this, then that," a common developer's phrase that indicates a relationship between two events. IFTTT takes that phrase and makes it simple to use for everyone. Want to automatically send your starred Google Reader items to Instapaper? Or get an SMS alert when your favorite comedian tweets that he's coming to your hometown? All easily done, with no development savvy required.
