There is a right way and a wrong way to chastise someone (or keep them on task). The previous blog post:

demonstrates the absolute wrong way.
I started to realize in about 5th grade (by watching a threatening, playground bully that everyone hated and a popular friendly kid that everyone liked) that there are ways to get people to do things you want them to do without pissing them off (Those you can't you just cast off and replace). Perhaps the author was the bully, or he missed the lesson.
Threatened, disgruntled employees will leave or worse (cause dissension, loss of productivity, they will take their frustration out on their peers and underlings, They will conspire against the threatening, abusive boss, poor morale will spread). I have witnessed this more than once already thus far in my 10 year career.
If warning them in a human adult-to-adult civilized manner does not work, and they continually demonstrates incompetence or insubordination, then replace them... no need to threaten them in such a harsh manner and blog about it like you just won a fistfight against a little kid (smacked em down good). You are not doing anyone any favors - trust me.
Your Abusive Ego may feel good, but your company will certainly suffer. Funny that your very claims for doing what you did are to make your company the best place to work - but in reality you just made it worse with your approach and choice of words.
This approach may sound new-age, feminine, soft, or touchy feely to you - but (in some ways) unfortunately it is the reality of today's tech worker's generation and how they expect to be treated (with some respect and consideration). Those who do not understand this, will repeatedly fail.
I say in some ways unfortunate - because it is taken way too far in way too many cases by today's young generation and they are simply lazy, unmotivated and have an entitlement attitude. Their expectation of respect and consideration is taken way too far (they expect to be coddled and never reprimanded). I am not changing my earlier viewpoints, I am simply establishing a foundation by which my statements should be based on.
