Some people are mean spirited and really are hard pressed to add any value to these posts. I just recently took a hit from someone on a blog on certifications just because he wasn't able to comprehend my posts, then tells me I need to work on my communications skills. Seriously, is it my fault that his comprehension level is where it is? I would say not, so I suggest just letting these people have the last word and don't bother trying to educate them because it usually won't work.
