I just get the keyword from my contractor (who in turn gets it from hi clients) and then google the term. If it is common enough there will be a wikipedia, ask.com or wikihow page. I just use that info. I can take a sentence in those websites and churn out 100-150 words on it. Its really easy to bloat articles (planning a blog post on all this).

I have also produced on academic paper (it was a position paper) and I instinctively avoided editing. I believe when you start editing a paper you often cut out the depth of the idea.
