"The reason these words are abused is because they work..."

Isn't this just an example of a bandwagon effect cognitive bias? How does the ubiquitous nature of bad copy make it any more effective? If anything, that's 180 degrees from true.

If every marketing statement could be taken at face value, this would work fine. Unfortunately, everyone has access to the same thesaurus I do. How am I distinguishable from my competitors if both our sites read like a checklist of abstractions?

Your point about the request processing number really drives this home. Whether someone prefers the word "powerful" as a stand-in for a demonstrative figure depends entirely on whether they're already inclined to believe whatever you say. If that is a good description of your average first-time visitor, then, um, I wouldn't waste much time on writing copy anyway. Just have a headline reading "This is exactly what you need." and a sign-up button.
