I agree with cover letters, but people get carried away with them. 
 
The objective of a cover letter is to get a perspective employee to read your resume or sell sheet. 
 
I keep mine three paragraphs long and as brief as possible. 
 
Para 1 - introduction and refirmation of the position I'm applying to. 
 
Para 2 - a brief overview of my top 3 relevant skills. 
 
Para 3 - Why the hell I'm the best match for the job.
