Begin Your Email with a Deadline to Get a Quicker Response?

I normally like Lifehacker's suggestions on productivity, but I'm a bit concerned about this.
Begin Your Email with a Deadline to Get a Quicker Response: "Skip the small talk and throw a deadline in the first sentence—for example, 'Attached, please see the draft of the Tuesday meeting notes, please reply with changes by 9 a.m. Monday.' Be clear about the deadline and the expected turn-around and don't waste their time with anything else. Check out the full post at Stepcase LIfehack for a few other helpful tips for inspiring prompt email replies."
A'm all for making a clear request. However, having been at the receiving end of terse emails in the workplace, I think that I would counsel the would-be writer of such emails to consider the emotional impact, paying particular attention to the possibility that if you already have prior record of dealing with people in a way that fails to acknowledge their difficulties, humanity or need for reasonable esteem, then an email of this type runs a high risk of coming over as officious or even with some kind of hinted criticism. Small talk can have the function of cementing, massaging, re-opening relationships. Failure to pay attention to the relational dimensions can be counter-productive. In this case, for instance non-co-operation from the colleague could be a way of reasserting their own power or sense of esteem.
