Leaving aside the issue of whether this is a valid point, which has been discussed to death already, what exactly are you getting at? Do you imagine the following scenario? Applicant: Pleeze hire me!!! 37signals: You misspelled "please", and used too many bangs. Next. Applicant: But you used two exclamation points on IRC in May 2006! 37signals: Ah, you caught me. In the interest of fairness, you're hired. You're supposed to apply far more scrutiny to a job application than just about any other document you ever write in your life, because you're competing against dozens of other people who are all attempting to make their best first impression as well, typically for a single opening. Those aren't good odds. That means write, read, reread, put it down and do something else to clear your head, come back and read it a third time, and then send. If you used that approach in every moment of every working day, you'd be absurdly unproductive. But if you can't be bothered to do it when it counts, can you really be trusted to act as an agent of the business these guys have poured their lives into building?
