I tossed resumes for even a single error, even if there was an MIT/Caltech/Stanford/Harvard/Yale degree on there. I did not want a low quality finished product to ever go out with my name on it. Not surprisingly, the people I hired under that standard did great work and many are now in business for themselves.
How about email address? There’s a story out there that aol or yahoo email makes you look old or unhip so you should change to gmail to look more cool. I’ve been a little disgusted with yahoo and thinking of changing to Reagan.com myself.
