Roger Dooley writes:
There are multiple reasons to choose verbs over adjectives. First, adjectives on their own don't say all that much and are easy to throw in without real justification. Describing a candidate as "dedicated, focused, and creative" is a quick way to satisfy the need for a favorable comment and get the recommendation on its way. Similarly, a product could be, "economical, long-lasting, and easy to use." In both cases, though, the reader has nothing to go on other than the word of the writer, who is almost certainly biased in favor of creating a good impression.
