Have you read the book name “Web Form Design” by Luke Wroblewski? If your answer is Yes then you must know there are Three known standards for placing the labels on the form. Left Align, Right Align and Top Align (from Field / Textbox). If your answer is in NO then fret not! Read the brief intro of it from Luke Wroblewski’s website http://www.lukew.com/ff/entry.asp?793 .
Again, see the screen-shot above from the Harvard Business Review’s Newsletter sign-up form (http://hbsp.ed4.net/prefcenter/signup.cfm). That’s an epic failure of the design. I see here that user will suffer the “Puzzle Thinking Syndrome” for such a small task. Why not follow the tried and true standards while developing the web forms, and put the Homo-Sapiens at ease.
