Proofread by another human . . . ?
I prefer to focus on people who can manage to turn in a resume that is grammatically correct, without spelling errors, without having to be proofread by another human being. I find that people who actually need spellcheckers are easily recognized by the fact that they believe the spellchecker -- which is often wrong somewhere in the midst of any complex document (like a resume).
Typos in public fora (such as this or the one at TR) are easily overlooked, but if you screw up a resume, there's something severely suboptimal going on.
