Subsection on active voice needs reorg

I suspect the entire subsection could do with a review, but this bit in
particular needs a rework:

For example, the sentence, "The Developer Center, a site for reference material and other resources, has been introduced to the OpenShift website." reads better than
"The OpenShift website introduces the Developer Center, a site for reference material and other resources." Here, the passive voice is better because the important issue ("The Developer Center") is the subject of the sentence.
