I can see the use being other for power users who want to have triggers for their own stuff "warn me if the cellphone bill is over the regular price so I check the overcharges". Myself if I go under my limit I have before the end of the day to correct the situation (I don't like to leave much money on the current account), so the first thing I would do is a simple script that warns me when that happens to avoid bank fees or even automatically correct if no correction had been done at 23h30. Or for companies who would like a processing pipeline that treat customer's orders once their wire payment arrive (send a confirmation email, activate the product, ...). Or of course like their snippet shows, for hip companies who want to post activities events on their social powered feed, because "bob bought bagels" is the information you need live at the office !
