Not just more likely, I flat out won't cold apply anywhere that doesn't have a range listed. I consider any company that isn't upfront about compensation as having something to hide.

Note: if you do this, mandatory salary field should be only numbers and dashes, because everyone will just do what craigslist does: "DOE", "Competitive" etc. See angellist for a good example of how to do this right.
