Example (not personal, you were just the top post right now): "Etsy.com is hiring all kinds of positions from engineering to design to marketing. Come join an awesome team..." I have no idea what you do or why that should interest me.
As opposed to: "Lot18 (http://www.lot18.com) is revolutionizing the way people buy wine and epicurean products online." Thank you, now I know whether I should continue reading based on whether that's something that interests me.
