It's a great idea and I hope the term "publishers" isn't limited to businesses. I always wanted a little service like this I could ask questions to: "I parked my car at the corner of Housten and Orchard, can someone confirm I don't have any tickets." "I heard XYZ closed down, can someone tell me if they're still in business."

Publishers -> someone who publishes tasks or has an audience of some sort. Not necessarily businesses.
