Ask Harley

I love to learn and I love to explain, so I guess it will make sense to you that one of my favorite pastimes is to think up interesting questions, do some research, figure out the answers, and then teach what I know to someone else.

Here is a list of such questions and answers that I hope you will enjoy reading.

I chose the questions so that each topic is related to one of the categories in my book, Harley Hahn's Internet Yellow Pages. At the end of each answer, I have put a link to the appropriate place in the book, in case you want to explore further.

In addition, a few of the questions relate to sections in one of my other books. In such cases, I have also included a link to these books as well.
